LETTER TO STOCKHOLDERS
                                                                       EXHIBIT 1

                       COMPUTER MANAGEMENT SCIENCES, INC.

                                                                February 9, 1999

Dear Fellow Shareholder:

      We are pleased to inform you that Computer Management Sciences, Inc.
("CMSI" or the "Company") has entered into an agreement with Computer Associates
International, Inc. ("CAI"), pursuant to which a wholly owned subsidiary of CAI
has commenced a tender offer today to purchase all the outstanding common stock
of CMSI for $28 per share, net to the seller in cash. Under the agreement, the
tender offer, if consummated, will be followed by a merger in which any 
remaining shares of CMSI common stock will be acquired for $28 per share, net 
to the seller in cash, or any higher price paid per share pursuant to the 
tender offer, and the Company will become a wholly owned subsidiary of CAI.

      Your Board of Directors ("Board") unanimously has determined that the
tender offer and the merger are fair to, and in the best interest of, the
Company's shareholders, has approved the offer and the merger, and recommends
that shareholders accept the offer and tender their shares pursuant to it. In
addition to the benefit of this transaction to our shareholders, we believe that
the combination will benefit greatly both companies.

      In connection with the transaction, certain executive officers and
directors of the Company and their affiliates have granted to CAI options to
acquire the approximately 30.8% of the outstanding common stock of the Company
owned by such persons, on a fully diluted basis.

      Accompanying this letter are CAI's Offer to Purchase, Letter of
Transmittal, and other related documents, together with the recommendation of
your Company's Board contained in the enclosed Schedule 14D-9. These documents
set forth the terms and conditions of the tender offer. In determining to
approve the merger agreement and the transactions contemplated by it, your Board
gave careful consideration to a number of factors described in the attached
Schedule 14D-9, which has been filed by the Company with the Securities and
Exchange Commission. Among other things, the Board considered the opinion of the
Company's financial advisor, The Robinson-Humphrey Company, LLC, to the effect
that, as of the date thereof, the consideration to be received by the
shareholders in the tender offer and in the merger is fair, from a financial
point of view, to them. The Schedule 14D-9 and CAI's Offer to Purchase describe
in more detail the reasons for the Board's conclusions and contain other
important information regarding the tender offer. The Board urges you to
consider this information carefully.

      CMSI's Board,  management,  and employees  thank you sincerely for your 
loyal support throughout the years. On behalf of the Board of Directors,

                                Sincerely,

                                 /S/ JERRY W. DAVIS
                                 Jerry W. Davis, Chairman of the Board and
                                 Chief Executive Officer
