Merrill Lynch
Senior Floating Rate
Fund, Inc.

Merrill Lynch Senior Floating Rate Fund, Inc. seeks as high a level
of current income and such preservation of capital as is consistent
with investment in senior collateralized corporate loans made by
banks and other financial institutions.

This report, including the financial information herein, is
transmitted for use only to the shareholders of Merrill Lynch Senior
Floating Rate Fund, Inc. for their information. It is not a
prospectus, circular or representation intended for use in the
purchase of shares of the Fund or any securities mentioned in this
report. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has the
ability to leverage its Common Stock to provide Common Stock
shareholders with a potentially higher rate of return. Leverage
creates risk for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of Common
Stock shares, and the risk that fluctuations in short-term interest
rates may reduce the Common Stock's yield. Statements and other
information herein are as dated and are subject to change.

DEAR SHAREHOLDER


Investment Approach
Merrill Lynch Senior Floating Rate Fund, Inc. consists largely of
participations in leveraged bank loans. These loans are generally
senior secured floating rate investments. In response to general
economic events and trends, the leveraged bank loan market tends to
move in a similar direction, but with less volatility, as the high-
yield bond market. The linkage between the two markets can be
ascribed to the fact that the issuers of debt as well as the buyers
of that debt tend to participate in both markets (based on similar
credit rating and risk/reward profiles of the markets). The lower
price volatility of bank loan investments can be attributed to two
factors. First, bank loans are usually senior secured obligations
and, thus, generally offer investors greater principal protection
than unsecured bonds. Second, bank loans are floating rate
instruments whose principal value does not move inversely with
interest rate movements, as is the case with fixed-income bonds.


Fund Performance
The Fund's effective net annualized yield for the six-month period
ended February 28, 2001 was 9.39%, compared to a yield of 7.83% for
the same period a year earlier. The Fund's net asset value decreased
from $9.45 per share to $9.10 per share during the period. During
the same period, the Fund earned $0.423 per share income dividends,
representing a net annualized yield of 9.39%, based on a per share
net asset value of $9.10 at February month-end. The Fund's total
investment return during the six-month period ended February 28,
2001 was +0.68%, based on a $0.36 per share decrease in net asset
value and assuming reinvestment of $0.428 per share income
dividends. Since inception (November 3, 1989) through February 28,
2001, the Fund's total investment return was +102.58%, based on a
change in per share net asset value from $10.00 to $9.10, and
assuming reinvestment of $8.008 per share income dividends.

The Fund's return of +0.68%, for the six-month period ended February
28, 2001, underperformed the unmanaged CS First Boston Leveraged
Loan Index, which had a return of +2.79%. During this period, the
Fund was underweighted relative to the Index in energy and
healthcare issues, two sectors that outperformed. The energy sector
benefited from the dramatic rise in commodity prices, while the
healthcare sector rebounded from its earlier very depressed levels.
The Fund was only slightly underweighted in energy (0.35% of net
assets compared to 0.47% in the Index) but, reflecting our
unfavorable experience with that sector in recent years, was
significantly underweighted in healthcare (3.9% compared to 9.4% in
the Index).


Market Review
The six-month period ended February 28, 2001 was marked by two
distinct trends in the high-yield and leveraged loan markets. During
the second half of 2000, these markets operated in a very negative
credit environment, culminating in total withdrawals from high-yield
mutual funds in excess of $10 billion for the year 2000. In 2001,
the markets began to rally in response to the Federal Reserve
Board's early interest rate cuts. Flows into the high-yield market
reversed course after the interest rate cuts and, through February,
total year-to-date inflows amounted to $3.25 billion. Since many
investors in the high-yield market also participate in the leveraged
bank loan market, the increased demand for leveraged finance product
caused by this additional market liquidity resulted in an increase
in market prices. Additionally, during the first two months of 2001,
high-yield spreads rebounded from a near record of 959 basis points
(9.59%) at year-end 2000, as measured by the unmanaged CS First
Boston Global High Yield Index, to 830 basis points (considerably
higher than the historic average of 529 basis points and the year-
end 1999 figure of 549 basis points).


Merrill Lynch Senior Floating Rate Fund, Inc.
February 28, 2001



Despite the improved tone of the market, there continues to be
concern about the overall default rate. During 1999, Moody's
Investors Service's dollar-weighted default rate for high-yield
bonds peaked at 7.8%, its highest level since 1991, before falling
back down to 6.2% by December 31, 2000. We believe that in 2001
default rates will yet again increase in response to the weakening
of certain sectors, including wired telecommunications and autos.
This expected increase is in line with historical trends, which show
that of the high-yield issues that eventually default, the majority
does so within three years - four years of issuance. Counting back
three years - four years from 2001 brings us back to the 1997 - 1998
period, which was generally characterized by lower credit standards
than existed in the years hence. Therefore, we believe that should
the historical trend hold, defaults could be expected to rise in
2001 from year-end 2000 levels, before falling back to more typical
levels in 2002.


Investment Activities
Pricing pressure in the wired telecommunications, computer-related
products, metals & mining and automotive sectors had the greatest
negative effect on the Fund during the period. In each of the first
two sectors, the majority of the impact was derived primarily from
one credit, while the problems in metals & mining and automotive
stemmed from an industrywide decline in revenues in a rising expense
environment. In wired telecommunications, our position in Teligent
Inc. declined almost 65 points. Teligent, a national competitive
local exchange carrier, has had the dual problems of revenue
shortfalls (driven by a decline in telecommunications access fees)
and management upheaval. We decided to remain invested in this issue
because of its asset value (wireless spectrum) and its notable
sponsor group. In the computer-related sector, Bridge Information
Systems also endured a precipitous decline. Bridge, a provider of
proprietary financial information services to the equity markets,
has been plagued with billing and integration issues and, during the
quarter, filed for bankruptcy. In the metals & mining sector,
falling commodity prices negatively affected steelmakers LTV
Corporation and Ispat Inland. As for the automotive equipment
suppliers in our portfolio, their use of aggressive pricing coupled
with a business model using lower production volumes left them
unprepared for overtime and adequate maintenance. The problems were
further aggravated by demands for price cuts by their customers, the
original equipment manufacturers.

On the positive side, the Fund continues to be anchored by
substantial investment in wireless telecommunications (11.2% of
total assets), cable television services (10%), hotels & motels
(5.9%) and broadcasting (4%). These sectors are characterized by
significant asset values and strong cashflow. At February 28, 2001,
the Fund's largest holdings were comprised largely of
representatives from these sectors, including Nextel Communications,
Inc., Charter Communications Holdings, Century Cable LLC and Wyndham
International, Inc. (For complete details of the Fund's largest
holdings and industries, see the "Portfolio Profile" section of this
report to shareholders on page 21.)

Investment Strategy
Thus far in 2001, we have seen some relief from the technical
aspects of the pricing pressure that had impacted the market so
significantly in 2000. This occurrence has allowed us to set the
course toward a reversal of the downward trend in the net asset
value by creating the liquidity needed to participate in a market
rally. Specifically, during this period, we have exited certain
lower-coupon issues that have regained par or near-par pricing
levels after a prolonged period of sub-par market values. The assets
created have been or will be redeployed into the new-issue market,
which continues to offer attractive spreads and original-issue
discounts, as well as in certain secondary situations where we still
see value.

We believe the Fund continues to be well balanced with 154 issuers
spread across 42 industries. The Fund also has an attractive ratings
profile as compared to the Index. The Fund was weighted almost
equally relative to the Index in Ba-rated securities (46.0% of total
assets compared to 48.6%), overweighted in B-rated securities (30.1%
compared to 25.4%), underweighted in Caa-rated securities (2.4%
compared to 4.4%) and slightly overweighted in securities not rated
(21.4% compared to 19.3%).

In Conclusion
We believe that, with adequate diversification and a solid credit
profile as its base, we can better position the Fund to take greater
advantage of any sustained reversal of technical price pressures on
the leveraged finance market. Our ability to bring this to fruition
will be challenged, as always, by any significant changes in
fundamental credit aspects of its issuers as well as the need to
meet future shareholder redemptions.

We thank you for your investment in Merrill Lynch Senior Floating
Rate Fund, Inc., and we look forward to reviewing our outlook and
strategy with you again in our next report to shareholders.

Sincerely,

THE BENEFITS AND RISKS OF LEVERAGING


Merrill Lynch Senior Floating Rate Fund, Inc. has the ability to
utilize leverage through borrowings or issuance of short-term debt
securities or shares of Preferred Stock. The concept of leveraging
is based on the premise that the cost of assets to be obtained from
leverage will be based on short-term interest rates, which normally
will be lower than the return earned by the Fund on its longer-term
portfolio investments. To the extent that the total assets of the
Fund (including the assets obtained from leverage) are invested in
higher-yielding portfolio investments, the Fund's Common Stock
shareholders will be the beneficiaries of the incremental yield.

Leverage creates risks for holders of Common Stock including the
likelihood of greater net asset value and market price volatility.
In addition, there is the risk that fluctuations in interest rates
on borrowings (or in the dividend rates on any Preferred Stock, if
the Fund were to issue the Preferred Stock) may reduce the Common
Stock's yield and negatively impact its market price. If the income
derived from securities purchased with assets received from leverage
exceeds the cost of leverage, the Fund's net income will be greater
than if leverage had not been used. Conversely, if the income from
the securities purchased is not sufficient to cover the cost of
leverage, the Fund's net income will be less than if leverage had
not been used, and therefore the amount available for distribution
to Common Stock shareholders will be reduced. In this case, the Fund
may nevertheless decide to maintain its leveraged position in order
to avoid capital losses on securities purchased with leverage.
However, the Fund will not generally utilize leverage if it
anticipates that its leveraged capital structure would result in a
lower rate of return for its Common Stock than would be obtained if
the Common Stock were unleveraged for any significant amount of
time.

As discussed in footnote 6 in the Notes to Financial Statements on
page 20, the Fund has not used this leverage capability.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Senior Floating Rate Fund, Inc. (the "Fund") is
registered under the Investment Company Act of 1940 as a
continuously offered, non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in
conformity with accounting principles generally accepted in the
United States of America, which may require the use of management
accruals and estimates. These unaudited financial statements reflect
all adjustments, which are, in the opinion of management, necessary
to a fair statement of the results for the interim period presented.
All such adjustments are of a normal, recurring nature.

(a) Loan participation interests--The Fund invests in senior secured
floating rate loan interests ("Loan Interests") with collateral
having a market value, at time of acquisition by the Fund, which
Fund management believes equals or exceeds the principal amount of
the corporate loan. The Fund may invest up to 20% of its total
assets in loans made on an unsecured basis. Depending on how the
loan was acquired, the Fund will regard the issuer as including the
corporate borrower along with an agent bank for the syndicate of
lenders and any intermediary of the Fund's investment. Because
agents and intermediaries are primarily commercial banks, the Fund's
investment in corporate loans at February 28, 2001 could be
considered to be concentrated in commercial banking.

(b) Valuation of investments--Loan Interests are valued in
accordance with guidelines established by the Board of Directors.
Loan Interests are valued at the mean between the last available bid
and asked prices from one or more brokers or dealers as obtained
from Loan Pricing Corporation. For the limited number of Loan
Interests for which no reliable price quotes are available, such
Loan Interests will be valued by Loan Pricing Corporation through
the use of pricing matrices to determine valuations. For Loan
Interests for which an active secondary market does not exist to a
reliable degree in the opinion of the Investment Adviser, such Loan
Interests will be valued by the Investment Adviser at fair value,
which is intended to approximate market value.

Other portfolio securities may be valued on the basis of prices
furnished by one or more pricing services, which determine prices
for normal, institutional-size trading units of such securities
using market information, transactions for comparable securities and
various relationships between securities that are generally
recognized by institutional traders. In certain circumstances,
portfolio securities are valued at the last sale price on the
exchange that is the primary market for such securities, or the last
quoted bid price for those securities for which the over-the-counter
market is the primary market or for listed securities in which there
were no sales during the day. Short-term securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market
quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of
Directors of the Fund.

(c) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies to increase or decrease the level of
risk to which the Fund is exposed more quickly and efficiently than
transactions in other types of instruments. Losses may arise due to
changes in the value of the contract or if the counterparty does not
perform under the contract.

* Interest rate transactions--The Fund is authorized to enter into
interest rate swaps and purchase or sell interest rate caps and
floors. In an interest rate swap, the Fund exchanges with another
party their respective commitments to pay or receive interest on a
specified notional principal amount. The purchase of an interest
rate cap (or floor) entitles the purchaser, to the extent that a
specified index exceeds (or falls below) a predetermined interest
rate, to receive payments of interest equal to the difference
between the index and the predetermined rate on a notional principal
amount from the party selling such interest rate cap (or floor).

(d) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.


Merrill Lynch Senior Floating Rate Fund, Inc.
February 28, 2001



(e) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Interest
income is recognized on the accrual basis. The Fund will adopt the
provisions to amortize all premiums and discounts on debt securities
effective October 1, 2001, as now required under the new AICPA Audit
and Accounting Guide for Investment Companies. The cumulative effect
of this accounting change will have no impact on the total net
assets of the Fund. The impact of this accounting change has not
been determined, but will result in an adjustment to the cost of
securities and a corresponding adjustment to net unrealized
appreciation/depreciation, based on securities held as of August 31,
2001.

(f) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(g) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates.


2. Investment Advisory and Administrative
Services Agreement and Transactions with
Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Merrill Lynch Investment Management, L.P. ("MLIM"). The general
partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect,
wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."),
which is the limited partner.

MLIM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to perform this investment advisory
function.

For such services, the Fund pays a monthly fee at an annual rate of
 .95% of the Fund's average daily net assets. The Fund also has an
Administrative Services Agreement with MLIM whereby MLIM will
receive a fee equal to an annual rate of .25% of the Fund's average
daily net assets on a monthly basis, in return for the performance
of administrative services (other than investment advice and related
portfolio activities) necessary for the operation of the Fund.

For the six months ended February 28, 2001, FAM Distributors, Inc.
("FAMD"), a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
earned early withdrawal charges of $1,624,826 relating to the tender
of the Fund's shares.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.

Accounting services were provided to the Fund by MLIM through
December 31, 2000. Up to this date, the Fund reimbursed MLIM
$164,926 for these services. As of January 1, 2001, accounting
services are provided for the Fund by State Street Bank and Trust
Company ("State Street") pursuant to an agreement between State
Street and the Fund. The Fund will pay the cost of these services.
In addition, the Fund will reimburse MLIM for the cost of certain
additional accounting services.
