ITEM 1. REPORTS TO STOCKHOLDERS.

The Report to Shareholders is attached herewith.


                              THE GABELLI ABC FUND
                                  ANNUAL REPORT
                               DECEMBER 31, 2008

TO OUR SHAREHOLDERS,

     The Sarbanes-Oxley Act requires a fund's principal executive and financial
officers to certify the entire contents of the semi-annual and annual
shareholder reports in a filing with the Securities and Exchange Commission on
Form N-CSR. This certification would cover the portfolio manager's commentary
and subjective opinions if they are attached to or a part of the financial
statements. Many of these comments and opinions would be difficult or impossible
to certify.

     Because we do not want our portfolio managers to eliminate their opinions
and/or restrict their commentary to historical facts, we have separated their
commentary from the financial statements and investment portfolio and have sent
it to you separately. Both the commentary and the financial statements,
including the schedule of investments, will be available on our website at
www.gabelli.com/funds.

     Enclosed are the audited financial statements and the investment portfolio
as of December 31, 2008 with a description of factors that affected the
performance during the past year.

PERFORMANCE DISCUSSION (UNAUDITED)

     The Gabelli ABC Fund (the "Fund") (Class AAA Shares) declined 2.63% in
2008.

     The Fund invests a portion of its assets in "event" driven situations such
as announced mergers, acquisitions, and reorganizations. When a company agrees
to be acquired by another company, its stock price often quickly rises to just
below the stated acquisition price. If the Adviser, through extensive research,
determines that the acquisition is likely to be consummated on schedule at the
stated acquisition price, then the Fund may purchase the selling company's
securities, offering the Fund the possibility of generous returns relative to
cash equivalents with a limited risk of capital.

     2008 was a period of upheaval in the equities market, and deal making was
not immune. As reported by Citi in its "Executive M&A Summary", the announced
deal volume for the year was $2.9 trillion - a reduction of 30% from the $4.2
trillion in 2007.

     Notwithstanding ongoing constraints in the credit markets, this is not a
trend we necessarily expect to continue. However, strategic buyers with the
financial wherewithal will continue to improve their market positions through
acquisition activity. We also expect to see an increase in financial engineering
- - spins and split-offs - as companies reposition themselves and seek to maximize
value.

     Holdings that contributed positively to performance in 2008 were UST Inc.
(21% of net assets as of December 31, 2008), Wm. Wrigley Jr., Anheuser-Busch,
and Foundry Networks. Detractors were Take-Two Interactive (0.5%), MGM Mirage
(0.3%), Rohm and Haas (4.0%), and Yahoo! (0.4%).

                                        Sincerely yours,


                                        /s/ Bruce N. Alpert

     PERFORMANCE RETURNS FOR PERIODS OF LESS THAN ONE YEAR ARE NOT ANNUALIZED.
     CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE DATA

     SHOULD BE READ CAREFULLY BEFORE INVESTING. THE S&P 500 INDEX IS AN
     UNMANAGED INDICATOR OF STOCK MARKET PERFORMANCE, WHILE THE LIPPER U.S.

     MUTUAL FUNDS CLASSIFIED IN THIS PARTICULAR CATEGORY. DIVIDENDS ARE
     CONSIDERED REINVESTED. YOU CANNOT INVEST DIRECTLY IN AN INDEX. THE CLASS
     AAA SHARES NET ASSET VALUES ("NAVS") PER SHARE ARE USED TO CALCULATE
     PERFORMANCE FOR THE PERIODS PRIOR TO THE ISSUANCE OF THE ADVISOR CLASS

THE GABELLI ABC FUND
DISCLOSURE OF FUND EXPENSES (UNAUDITED)
For the Six Month Period from July 1, 2008 through
December 31, 2008                                                  EXPENSE TABLE

We believe it is important for you to understand the impact of fees and expenses
regarding your investment. All mutual funds have operating expenses. As a
shareholder of a fund, you incur ongoing costs, which include costs for
portfolio management, administrative services, and shareholder reports (like
this one), among others. Operating expenses, which are deducted from a fund's
gross income, directly reduce the investment return of a fund. When a fund's
expenses are expressed as a percentage of its average net assets, this figure is
known as the expense ratio. The following examples are intended to help you
understand the ongoing costs (in dollars) of investing in your Fund and to
compare these costs with those of other mutual funds. The examples are based on
an investment of $1,000 made at the beginning of the period shown and held for
the entire period.

The Expense Table below illustrates your Fund's costs in two ways:

ACTUAL FUND RETURN: This section provides information about actual account
values and actual expenses. You may use this section to help you to estimate the
actual expenses that you paid over the period after any fee waivers and expense
reimbursements. The "Ending Account Value" shown is derived from the Fund's
ACTUAL return during the past six months, and the "Expenses Paid During Period"
shows the dollar amount that would have been paid by an investor who started
with $1,000 in the Fund. You may use this information, together with the amount
you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
given for your Fund under the heading "Expenses Paid During Period" to estimate
the expenses you paid during this period.

HYPOTHETICAL 5% RETURN: This section provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio. It assumes a hypothetical annualized return of 5% before expenses during
the period shown. In this case - because the hypothetical return used is NOT the
Fund's actual return - the results do not apply to your investment and you
cannot use the hypothetical account value and expense to estimate the actual
ending account balance or expenses you paid for the period. This example is
useful in making comparisons of the ongoing costs of investing in the Fund and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as sales
charges (loads), redemption fees, or exchange fees, if any, which are described
in the Prospectus. If these costs were applied to your account, your costs would
be higher. Therefore, the 5% hypothetical return is useful in comparing ongoing
costs only, and will not help you determine the relative total costs of owning
different funds. The "Annualized Expense Ratio" represents the actual expenses
for the last six months and may be different from the expense ratio in the
Financial Highlights which is for the year ended December 31, 2008.

     by the number of days in the most recent fiscal half-year, then divided by

(c)  The Fund incurred interest expense during the years ended December 31, 2007
     and 2006. If interest expense had not been incurred, the ratio of operating
     expenses to average net assets would have been 0.63% and 0.61% for Class
     AAA, and 0.88% for the period ended December 31, 2007 for the Advisor
     Class. For the year ended December 31, 2008, the effect of interest expense
     was minimal.

THE GABELLI ABC FUND
NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION. The Gabelli ABC Fund (the "Fund"), a series of Gabelli Investor
Funds, Inc. (the "Corporation"), was organized on October 30, 1992 as a Maryland
corporation. The Fund is a non-diversified open-end management investment
company registered under the Investment Company Act of 1940, as amended (the
"1940 Act"). The Fund's primary objective is to achieve total returns that are
attractive to investors in various market conditions without excessive risk of
capital loss. The Fund commenced investment operations on May 14, 1993. On
February 21, 2007, the Board of Directors (the "Board") reclassified the Fund's
shares into Class AAA Shares and Advisor Class Shares and reallocated the
authorized shares evenly between these Share Classes. Advisor Class Shares were
first issued on May 1, 2007.

2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in
accordance with United States ("U.S.") generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates. The following is a summary of significant accounting
policies followed by the Fund in the preparation of its financial statements.

SECURITY VALUATION. Portfolio securities listed or traded on a nationally
recognized securities exchange or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's official closing price as of the close of business on the
day the securities are being valued. If there were no sales that day, the
security is valued at the average of the closing bid and asked prices or, if
there were no asked prices quoted on that day, then the security is valued at
the closing bid price on that day. If no bid or asked prices are quoted on such
day, the security is valued at the most recently available price or, if the
Board so determines, by such other method as the Board shall determine in good
faith to reflect its fair market value. Portfolio securities traded on more than
one national securities exchange or market are valued according to the broadest
and most representative market, as determined by Gabelli Funds, LLC (the
"Adviser").

Portfolio securities primarily traded on a foreign market are generally valued
at the preceding closing values of such securities on the relevant market, but
may be fair valued pursuant to procedures established by the Board if market
conditions change significantly after the close of the foreign market but prior
to the close of business on the day the securities are being valued. Debt
instruments with remaining maturities of 60 days or less that are not credit
impaired are valued at amortized cost, unless the Board determines such amount
does not reflect the securities' fair value, in which case these securities will
be fair valued as determined by the Board. Debt instruments having a maturity
greater than 60 days for which market quotations are readily available are
valued at the average of the latest bid and asked prices. If there were no asked
prices quoted on such day, the security is valued using the closing bid price.
Futures contracts are valued at the closing settlement price of the exchange or
board of trade on which the applicable contract is traded.

Securities and assets for which market quotations are not readily available are
fair valued as determined by the Board. Fair valuation methodologies and
procedures may include, but are not limited to: analysis and review of available
financial and non-financial information about the company; comparisons with the
valuation and changes in valuation of similar securities, including a comparison
of foreign securities with the equivalent U.S. dollar value ADR securities at
the close of the U.S. exchange; and evaluation of any other information that
could be indicative of the value of the security.

Statement of Financial Accounting Standard No. 157, "Fair Value Measurements"
("SFAS 157") clarifies the definition of fair value for financial reporting,
establishes a framework for measuring fair value, and requires additional
disclosures about the use of fair value measurements. The three levels of the
fair value hierarchy under SFAS 157 are described below:

     -    Level 1 - quoted prices in active markets for identical securities;


                                       12



THE GABELLI ABC FUND

     -    Level 2 - other significant observable inputs (including quoted prices
          for similar securities, interest rates, prepayment speeds, credit
          risk, etc.); and

     -    Level 3 - significant unobservable inputs (including the Fund's
          determinations as to the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. The
summary of the Fund's investments and other financial instruments, by inputs
used to value the Fund's investments as of December 31, 2008 is, as follows:

In March 2008, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standard No. 161, "Disclosures about
Derivative Instruments and Hedging Activities" ("SFAS 161") that is effective
for fiscal years beginning after November 15, 2008. SFAS 161 is intended to
improve financial reporting for derivative instruments by requiring enhanced
disclosure that enables investors to understand how and why an entity uses
derivatives, how derivatives are accounted for, and how derivative instruments
affect an entity's results of operations and financial position. Management is
currently evaluating the implications of SFAS 161 on the Fund's financial
statement disclosures.

REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements with
primary government securities dealers recognized by the Federal Reserve Board,
with member banks of the Federal Reserve System, or with other brokers or
dealers that meet credit guidelines established by the Adviser and reviewed by
the Board. Under the terms of a typical repurchase agreement, the Fund takes
possession of an underlying debt obligation subject to an obligation of the
seller to repurchase, and the Fund to resell, the obligation at an agreed-upon
price and time,


                                       13



THE GABELLI ABC FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

thereby determining the yield during the Fund's holding period. It is the policy
of the Fund to always receive and maintain securities as collateral whose market
value, including accrued interest, are at least equal to 102% of the dollar
amount invested by the Fund in each agreement. The Fund will make payment for
such securities only upon physical delivery or upon evidence of book entry
transfer of the collateral to the account of the custodian. To the extent that
any repurchase transaction exceeds one business day, the value of the collateral
is marked-to-market on a daily basis to maintain the adequacy of the collateral.
If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings are commenced with respect to the seller of the security,
realization of the collateral by the Fund may be delayed or limited. At December
31, 2008, there were no open repurchase agreements.

SWAP AGREEMENTS. The Fund may enter into equity and contract for difference swap
transactions. The use of swaps is a highly specialized activity that involves
investment techniques and risks different from those associated with ordinary
portfolio security transactions. In a swap, a set of future cash flows are
exchanged between two counterparties. One of these cash flow streams will
typically be based on a reference interest rate combined with the performance of
a notional value of shares of a stock. The other will be based on the
performance of the shares of a stock. There is no assurance that the swap
contract counterparties will be able to meet their obligations pursuant to the
swap contracts, or that, in the event of default, the Fund will succeed in
pursuing contractual remedies. The Fund thus assumes the risk that it may be
delayed in or prevented from obtaining payments owed to it pursuant to the swap
contracts. The creditworthiness of the swap contract counterparties is closely
monitored in order to minimize the risk. Depending on the general state of
short-term interest rates and the returns of the Fund's portfolio securities at
that point in time, such a default could negatively affect the Fund's ability to
make dividend payments. In addition, at the time a swap transaction reaches its
scheduled termination date, there is a risk that the Fund will not be able to
obtain a replacement transaction or that the terms of the replacement will not
be as favorable as on the expiring transaction. If this occurs, it could have a
negative impact on the Fund's ability to make dividend payments.

The use of derivative instruments involves, to varying degrees, elements of
market and counterparty risk in excess of the amount recognized below.

Unrealized gains related to swaps are reported as an asset and unrealized losses
are reported as a liability in the Statement of Assets and Liabilities. The
change in value of swaps, including the accrual of periodic amounts of interest
to be paid or received on swaps, is reported as unrealized gains or losses in
the Statement of Operations. A realized gain or loss is recorded upon payment or
receipt of a periodic payment or termination of swap agreements.

Effective March 16, 2008, Bear, Stearns International Limited entered into a
Guaranty Agreement with JPMorgan Chase & Co., whereby JPMorgan Chase & Co.
unconditionally guarantees the due and punctual payment of certain liabilities
of Bear, Stearns International Limited, including the current liabilities of
Bear, Stearns International Limited to the Fund. As of December 31, 2008, the
Fund held a contract for difference swap with Bear, Stearns International
Limited which is covered by the JPMorgan Chase & Co. Guaranty Agreement as of
the date of the report. Details of the swap at December 31, 2008 are as follows:

THE GABELLI ABC FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

FUTURES CONTRACTS. The Fund may engage in futures contracts for the purpose of
hedging against changes in the value of its portfolio securities and in the
value of securities it intends to purchase. Upon entering into a futures
contract, the Fund is required to deposit with the broker an amount of cash or
cash equivalents equal to a certain percentage of the contract amount. This is
known as the "initial margin." Subsequent payments ("variation margin") are made
or received by the Fund each day, depending on the daily fluctuations in the
value of the contract, which are included in unrealized
appreciation/depreciation on investments and futures contracts. The Fund
recognizes a realized gain or loss when the contract is closed.

There are several risks in connection with the use of futures contracts as a
hedging instrument. The change in value of futures contracts primarily
corresponds with the value of their underlying instruments, which may not
correlate with the change in value of the hedged investments. In addition, there
is the risk that the Fund may not be able to enter into a closing transaction
because of an illiquid secondary market. At December 31, 2008, there were no
open futures contracts.

SECURITIES SOLD SHORT. The Fund may enter into short sale transactions. Short
selling involves selling securities that may or may not be owned and, at times,
borrowing the same securities for delivery to the purchaser, with an obligation
to replace such borrowed securities at a later date. The proceeds received from
short sales are recorded as liabilities and the Fund records an unrealized gain
or loss to the extent of the difference between the proceeds received and the
value of an open short position on the day of determination. The Fund records a
realized gain or loss when the short position is closed out. By entering into a
short sale, the Fund bears the market risk of an unfavorable change in the price
of the security sold short. Dividends on short sales are recorded as an expense
by the Fund on the ex-dividend date and interest expense is recorded on the
accrual basis. The Fund did not hold any short positions as of December 31,
2008.

FORWARD FOREIGN EXCHANGE CONTRACTS. The Fund may engage in forward foreign
exchange contracts for hedging a specific transaction with respect to either the
currency in which the transaction is denominated or another currency as deemed
appropriate by the Adviser. Forward foreign exchange contracts are valued at the
forward rate and are marked-to-market daily. The change in market value is
included in unrealized appreciation/depreciation on investments and foreign
currency translations. When the contract is closed, the Fund records a realized
gain or loss equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

The use of forward foreign exchange contracts does not eliminate fluctuations in
the underlying prices of the Fund's portfolio securities, but it does establish
a rate of exchange that can be achieved in the future. Although forward foreign
exchange contracts limit the risk of loss due to a decline in the value of the
hedged currency, they also limit any potential gain that might result should the
value of the currency increase. In addition, the Fund could be exposed to risks
if the counterparties to the contracts are unable to meet the terms of their
contracts. At December 31, 2008, there were no open forward foreign exchange
contracts.

FOREIGN CURRENCY TRANSLATIONS. The books and records of the Fund are maintained
in U.S. dollars. Foreign currencies, investments, and other assets and
liabilities are translated into U.S. dollars at the current exchange rates.
Purchases and sales of investment securities, income, and expenses are
translated at the exchange rate prevailing on the respective dates of such
transactions. Unrealized gains and losses that result from changes in foreign
exchange rates and/or changes in market prices of securities have been included
in unrealized appreciation/depreciation on investments and foreign currency
translations. Net realized foreign currency gains

and losses resulting from changes in exchange rates include foreign currency
gains and losses between trade date and settlement date on investment securities
transactions, foreign currency transactions, and the difference between the
amounts of interest and dividends recorded on the books of the Fund and the
amounts actually received. The portion of foreign currency gains and losses
related to fluctuation in exchange rates between the initial trade date and
subsequent sale trade date is included in realized gain/(loss) on investments.

FOREIGN SECURITIES. The Fund may directly purchase securities of foreign
issuers. Investing in securities of foreign issuers involves special risks not
typically associated with investing in securities of U.S. issuers. The risks
include possible revaluation of currencies, the ability to repatriate funds,
less complete financial information about companies, and possible future adverse
political and economic developments. Moreover, securities of many foreign
issuers and their markets may be less liquid and their prices more volatile than
those of securities of comparable U.S. issuers.

FOREIGN TAXES. The Fund may be subject to foreign taxes on income, gains on
investments, or currency repatriation, a portion of which may be recoverable.
The Fund will accrue such taxes and recoveries as applicable, based upon its
current interpretation of tax rules and regulations that exist in the markets in
which it invests.

RESTRICTED AND ILLIQUID SECURITIES. The Fund may invest up to 15% of its net
assets in securities for which the markets are illiquid. Illiquid securities
include securities the disposition of which is subject to substantial legal or
contractual restrictions. The sale of illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Securities freely saleable among qualified
institutional investors under special rules adopted by the SEC may be treated as
liquid if they satisfy liquidity standards established by the Board. The
continued liquidity of such securities is not as well assured as that of
publicly traded securities, and accordingly the Board will monitor their
liquidity.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are
accounted for on the trade date with realized gain or loss on investments
determined by using the identified cost method. Interest income (including
amortization of premium and accretion of discount) is recorded on the accrual
basis. Premiums and discounts on debt securities are amortized using the
effective yield to maturity method. Dividend income is recorded on the
ex-dividend date except for certain dividends which are recorded as soon as the
Fund is informed of the dividend.

DETERMINATION OF NET ASSET VALUE AND CALCULATION OF EXPENSES. Certain
administrative expenses are common to, and allocated among, various affiliated
funds. Such allocations are made on the basis of each Fund's average net assets
or other criteria directly affecting the expenses as determined by the Adviser
pursuant to procedures established by the Board.

In calculating the NAV per share of each class, investment income, realized and
unrealized gains and losses, redemption fees, and expenses other than class
specific expenses, are allocated daily to each class of shares based upon the
proportion of net assets of each class at the beginning of each day.
Distribution expenses are borne solely by the class incurring the expense.

CUSTODIAN FEE CREDITS AND INTEREST EXPENSE. When cash balances are maintained in
the custody account, the Fund receives credits which are used to offset
custodian fees. The gross expenses paid under the custody


                                       16



THE GABELLI ABC FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

arrangement are included in custodian fees in the Statement of Operations with
the corresponding expense offset, if any, shown as "custodian fee credits." When
cash balances are overdrawn, the Fund is charged an overdraft fee equal to 2.00%
above the federal funds rate on outstanding balances. This amount, if any, would
be included in "interest expense" in the Statement of Operations.

DISTRIBUTIONS TO SHAREHOLDERS. Distributions to shareholders are recorded on the
ex-dividend date. Distributions to shareholders are based on income and capital
gains as determined in accordance with federal income tax regulations, which may
differ from income and capital gains as determined under U.S. generally accepted
accounting principles. These differences are primarily due to differing
treatments of income and gains on various investment securities and foreign
currency transactions held by the Fund, timing differences, and differing
characterizations of distributions made by the Fund. Distributions from net
investment income include net realized gains on foreign currency transactions.
These book/tax differences are either temporary or permanent in nature. To the
extent these differences are permanent, adjustments are made to the appropriate
capital accounts in the period when the differences arise. These
reclassifications have no impact on the NAV of the Fund, including the Fund's
use of the tax accounting practice known as equalization, the utilization of
earnings and profits distributed to shareholders on redemption of shares as part
of the dividends-paid deduction for federal income tax purposes. For the year
ended December 31, 2008, reclassifications were made to decrease accumulated net
investment income by $780,856 and to increase accumulated distributions in
excess of net realized gain on investments, swap contracts, and foreign currency
transactions by $1,036,276, with an offsetting adjustment to paid-in capital.

The tax character of distributions paid during the years ended December 31, 2008
and December 31, 2007 was as follows:

PROVISION FOR INCOME TAXES. The Fund intends to continue to qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (the "Code"). It is the policy of the Fund to comply with the
requirements of the Code applicable to regulated investment companies and to
distribute substantially all of its net investment company taxable income and
net capital gains. Therefore, no provision for federal income taxes is required.

At December 31, 2008, the difference between book basis and tax basis unrealized
depreciation was primarily due to deferral of losses from wash sales for tax
purposes.

As of December 31, 2008, the components of accumulated earning/losses on a tax
basis were as follows:

FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN
48") provides guidance for how uncertain tax positions should be recognized,
measured, presented, and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the "more-likely-than-not" threshold are recorded
as a tax benefit or expense in the current year. In accordance with FIN 48,
management has analyzed the Fund's tax positions taken on the federal and state
income tax returns for all open tax years (the current and prior three tax
years) and has concluded that no provision for income tax is required in the
Fund's financial statements. Management's determination regarding FIN 48 may be
subject to review and adjustment at a later date based on factors including, but
not limited to, an on-going analysis of tax laws, regulations, and
interpretations thereof.

3. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS. The Fund has entered
into an investment advisory agreement (the "Advisory Agreement") with the
Adviser which provides that the Fund will pay the Adviser a fee, computed daily
and paid monthly, at the annual rate of 0.50% of the value of its average daily
net assets. In accordance with the Advisory Agreement, the Adviser provides a
continuous investment program for the Fund's portfolio, oversees the
administration of all aspects of the Fund's business and affairs, and pays the
compensation of all Officers and Directors of the Fund who are affiliated
persons of the Adviser.

The Fund pays each Director who is not considered to be an affiliated person an
annual retainer of $1,000 plus $250 for each Board meeting attended and they are
reimbursed for any out of pocket expenses incurred in attending meetings. All
Board committee members receive $250 per meeting attended and the Chairman of
the Audit Committee and the Lead Director each receives a $1,000 annual fee.
Directors who are directors or employees of the Adviser or an affiliated company
receive no compensation or expense reimbursement from the Fund.

4. DISTRIBUTION PLAN. The Fund's Board has adopted a distribution plan (the
"Plan") for the Advisor Class Shares pursuant to Rule 12b-1 under the 1940 Act.
Gabelli & Company, Inc. ("Gabelli & Company"), an affiliate of the Adviser,
serves as distributor of the Fund. Under the Advisor Class Share Plan, payment
is authorized to Gabelli & Company at an annual rate of 0.25% of the average
daily net assets of the Advisor Class Shares, the annual limitation under the
Plan. Such payments are accrued daily and paid monthly.

5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities
during 2008, other than short-term securities and U.S. Government obligations,
aggregated $537,389,344 and $511,643,074, respectively.

Purchases and proceeds from the sales of U.S. Government obligations during
2008, other than short-term obligations, aggregated $19,170,112 and $19,430,736,
respectively.

6. TRANSACTIONS WITH AFFILIATES. During 2008, the Fund paid brokerage
commissions on security trades of $230,614 to Gabelli & Company.

The cost of calculating the Fund's NAV per share is a Fund expense pursuant to
the Advisory Agreement between the Fund and the Adviser. During 2008, the Fund
paid or accrued $45,000 to the Adviser in connection with the cost of computing
the Fund's NAV.

7. LINE OF CREDIT. The Fund participates in an unsecured line of credit of up to
$75,000,000 from which it may borrow up to 10% of its net assets from the
custodian for temporary borrowing purposes. Borrowings under this arrangement
bear interest at 0.75% above the federal funds rate on outstanding balances.
This amount, if any, would be included in "interest expense" in the Statement of
Operations. During 2008, there were no borrowings under the line of credit.

8. CAPITAL STOCK. The Fund offers Class AAA Shares and Advisor Class Shares to
investors without a front-end sales charge. Class AAA Shares are available
directly through the distributor or through the Fund's transfer agent. Advisor
Class Shares are available through registered broker-dealers or other financial
intermediaries that have entered into appropriate selling agreements with the
distributor.

The Fund imposes a redemption fee of 2.00% on all classes of shares that are
redeemed or exchanged on or before the seventh day after the date of a purchase.
The redemption fee is deducted from the proceeds otherwise payable to the
redeeming shareholders and is retained by the Fund. The redemption fees retained
by the Fund during the years ended December 31, 2008 and December 31, 2007
amounted to $714 and $85, respectively.

The redemption fee does not apply to redemptions of shares where (i) the shares
were purchased through automatic reinvestment of distributions, (ii) the
redemption was initiated by the Fund, (iii) the shares were purchased through
programs that collect the redemption fee at the program level and remit them to
the Fund, or (iv) the shares were purchased through programs that the Adviser
determines to have appropriate anti-short-term trading policies in place or as
to which the Adviser has received assurances that look-through redemption fee
procedures or effective anti-short-term trading policies and procedures are in
place.

Transactions in shares of capital stock were as follows:

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

9. INDEMNIFICATIONS. The Fund enters into contracts that contain a variety of
indemnifications. The Fund's maximum exposure under these arrangements is
unknown. However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

10. OTHER MATTERS. On April 24, 2008, the Adviser entered into an administrative
settlement with the SEC to resolve the SEC's inquiry regarding prior frequent
trading activity in shares of the GAMCO Global Growth Fund (the "Global Growth
Fund") by one investor who was banned from the Global Growth Fund in August
2002. In the settlement, the SEC found that the Adviser had violated Section
206(2) of the Investment Advisers Act, Section 17(d) of the 1940 Act, and Rule
17d-1 thereunder and had aided and abetted and caused violations of Section
12(d)(1)(B)(i) of the 1940 Act. Under the terms of the settlement, the Adviser,
while neither admitting nor denying the SEC's findings and allegations, agreed,
among other things, to pay the previously reserved total of $16 million
(including a $5 million penalty), of which at least $11 million will be
distributed to shareholders of the Global Growth Fund in accordance with a plan
to be developed by an independent distribution consultant and approved by the
independent directors of the Global Growth Fund and the staff of the SEC and to
cease and desist from future violations of the above referenced federal
securities laws. The settlement is not expected to impact the Fund and will not
have a material adverse impact on the Adviser or its ability to fulfill its
obligations under the Advisory Agreement. On the same day, the SEC filed a civil
action against the Executive Vice President and Chief Operating Officer of the
Adviser, alleging violations of certain federal securities laws arising from the
same matter. The officer is also an officer of the Global Growth Fund and other
funds in the Gabelli/GAMCO fund complex including the Fund. The officer denies
the allegations and is continuing in his positions with the Adviser and the
funds. The Adviser currently expects that any resolution of the action against
the officer will not have a material adverse impact on the Adviser or its
ability to fulfill its obligations under the Advisory Agreement.

In a separate matter, on January 12, 2009, the SEC issued an administrative
action approving a final settlement of a previously disclosed matter with the
Adviser involving compliance with Section 19(a) of the Investment Company Act of
1940 and Rule 19a-1 thereunder by two closed-end funds. These provisions require
registered investment companies when making a distribution in the nature of a
dividend from sources other than net investment income to contemporaneously
provide written statements to shareholders, which adequately disclose the source
or sources of such distribution. While the two funds sent annual statements and
provided other materials containing this information, the shareholders did not
receive the notices required by Rule 19a-1 with any of the distributions that
were made for 2002 and 2003. The Adviser believes that the funds have been in
compliance with Section 19(a) and Rule 19a-1 since the beginning of 2004. As
part of the settlement, in which the Adviser neither admits nor denies the
findings by the SEC, the Adviser agreed to pay a civil monetary penalty of
$450,000 and to cease and desist from causing violations of Section 19(a) and
Rule 19a-1. In connection with the settlement, the SEC noted the remedial
actions previously undertaken by the Adviser.

THE GABELLI ABC FUND
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of
Gabelli Investor Funds, Inc.

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of The Gabelli ABC Fund (the "Fund"), a series of
Gabelli Investor Funds, Inc., as of December 31, 2008, and the related statement
of operations for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2008, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of The
Gabelli ABC Fund, a series of Gabelli Investor Funds, Inc., at December 31,
2008, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in conformity
with U.S. generally accepted accounting principles.

                   2008 TAX NOTICE TO SHAREHOLDERS (Unaudited)

For the year ended December 31, 2008, the Fund paid to shareholders an ordinary
income distribution (comprised of net investment income and short-term capital
gains) totaling $0.263 and $0.233 per share for Class AAA and Advisor Class,
respectively. For the year ended December 31, 2008, 20.91% of the ordinary
income distribution qualifies for the dividends received deduction available to
corporations. The Fund designates 22.34% of the ordinary income distribution as
qualified dividend income pursuant to the Jobs and Growth Tax Relief
Reconciliation Act of 2003. The Fund designates 26.18% of the ordinary income
distribution as qualified interest income, and 64.70% of the ordinary income
distribution as qualified short-term gain, pursuant to the American Jobs
Creation Act of 2004.

U.S. GOVERNMENT INCOME:

The percentage of the ordinary income distribution paid by the Fund during 2008
which was derived from U.S. Treasury securities was 23.36%. Such income is
exempt from state and local tax in all states. However, many states, including
New York and California, allow a tax exemption for a portion of the income
earned only if a mutual fund has invested at least 50% of its assets at the end
of each quarter of the Fund's fiscal year in U.S. Government securities. The
Gabelli ABC Fund did not meet this strict requirement in 2008. The percentage of
net assets of U.S. Government securities held as of December 31, 2008 was
30.09%. Due to the diversity in state and local tax law, it is recommended that
you consult your personal tax adviser as to the applicability of the information
provided to your specific situation.

All designations are based on financial information available as of the date of
this annual report and, accordingly, are subject to change. For each item, it is
the intention of the Fund to designate the maximum amount permitted under the
Internal Revenue Code and the regulations thereunder.

         Pre-Approval Policies and Procedures. The Audit Committee ("Committee")
         of the registrant is responsible for pre-approving (i) all audit and
         permissible non-audit services to be provided by the independent
         registered public accounting firm to the registrant and (ii) all
         permissible non-audit services to be provided by the independent
         registered public accounting firm to the Adviser, Gabelli Funds, LLC,
         and any affiliate of Gabelli Funds, LLC ("Gabelli") that provides
         services to the registrant (a "Covered Services Provider") if the
         independent registered public accounting firm's engagement related
         directly to the operations and financial reporting of the registrant.
         The Committee may delegate its responsibility to pre-approve any such
         audit and permissible non-audit services to the Chairperson of the
         Committee, and the Chairperson must report to the Committee, at its
         next regularly scheduled meeting after the Chairperson's pre-approval
         of such services, his or her decision(s). The Committee may also
         establish detailed pre-approval policies and procedures for
         pre-approval of such services in accordance with applicable laws,
         including the delegation of some or all of the Committee's pre-approval
         responsibilities to the other persons (other than Gabelli or the
         registrant's officers). Pre-approval by the Committee of any
         permissible non-audit services is not required so long as: (i) the
         permissible non-audit services were not recognized by the registrant at
         the time of the engagement to be non-audit services; and (ii) such
         services are promptly brought to the attention of the Committee and
         approved by the Committee or Chairperson prior to the completion of the
         audit.

  (e)(2) The percentage of services described in each of paragraphs (b) through
         (d) of this Item that were approved by the audit committee pursuant to
         paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are as follows:

                           (b) Not applicable

                           (c) 100%

                           (d) Not applicable

     (f) The percentage of hours expended on the principal accountant's
         engagement to audit the registrant's financial statements for the most
         recent fiscal year that were attributed to work performed by persons
         other than the principal accountant's full-time, permanent employees
         was zero percent (0%).


     (g) The aggregate non-audit fees billed by the registrant's accountant for
         services rendered to the registrant, and rendered to the registrant's
         investment adviser (not including any sub-adviser whose role is
         primarily portfolio management and is subcontracted with or overseen by
         another investment adviser), and any entity controlling, controlled by,
         or under common control with the adviser that provides ongoing services
         to the registrant for each of the last two fiscal years of the
         registrant was $69,100 for 2007 and $4,300 for 2008.

     (h) The registrant's audit committee of the board of directors has
         considered whether the provision of non-audit services that were
         rendered to the registrant's investment adviser (not including any
         sub-adviser whose role is primarily portfolio management and is
         subcontracted with or overseen by another investment adviser), and any
         entity controlling, controlled by, or under common control with the
         investment adviser that provides ongoing services to the registrant
         that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
         2-01 of Regulation S-X is compatible with maintaining the principal
         accountant's independence.

         90 days of the filing date of the report that includes the disclosure
         required by this paragraph, based on their evaluation of these controls
         and procedures required by Rule 30a-3(b) under the 1940 Act (17 CFR
         270.30a-3(b)) and Rules 13a-15(b) or 15d-15(b) under the Securities
         Exchange Act of 1934, as amended (17 CFR 240.13a-15(b) or

         financial reporting (as defined in Rule 30a-3(d) under the 1940 Act (17
         CFR 270.30a-3(d)) that occurred during the registrant's second fiscal
