File Number S360-24 Form C28-6570-0 Systems Reference Library IBM System/360 Transition Aids COBOL Language Differences This publication sumroarizes the System/360 and Current Systems specifications for major IBM COBOL language elements requiring evaluation, and possible conversion, during the transition to IBM System/360 COBOL. System/360 COBOL differences from Current Systems COBOL are also summarized. Where pertinent, the distinction is made between Level E and Level F CCBOL for System/360. PREFACE This publication provides a convenient reference to the major language differences between the IBM Current Systems COBOL languages and the IBM System/360 COBOL language. The information presented in this publication was drawn from the existing IBM COBOL Language manuals (listed under "Prerequisite Knowledge") that contain the specifications for all the Current Systems compilers and the System/360 COBOL compiler. The material presented is entirely dependent upon these publications and derives its authority from them. In cases of conflict this publication does not supersede any of the publications. PREREQUISITE KNCWLEDGE The reader of this publication should have a basic knowledge of the COBOL language, as well as a working knowledge of at least one IBM COBOL compiler. System/360 COBOL is described in IEM System/360 Operating Systems; COBOL Language, Form C28-6516-2. The basic COBOL language implemented by the IBM Current Systems compilers is described in Common Business Oriented Language (COBOL); General Information Form F28-8053. In most instances, the specifi- cations contained in the tables in this publication are in addition to the specifications contained in the general information manual. There- fore, a thorough familiarity with the general information manual is essential to the effective use of this publication. Additional specifications for the individual Current Systems Compil- ers are contained in the following publications: COBOL (on Tape) Specifications; IBM 1401, Form C24-1492-1. COBOL (on Disk) Specifications; IBM 1401, 1440, and 1460, Form C24-3235-1. IBM 1410/7010 Operating System; COBOL L Form C28-0327-2. IBM 7040/7044 Operating Systems (16/32K) COBOL Language, Form C28-6336-2. IBM 7070-Series Programming Systems; COBOL Processor, Form J28-6182-2. IBM 7070-Series COBOL/FORTRAN Operating System; COBOL, Form C28-6901-1. IBM 705/7080 Programming Systems; COBOL: Additional Specifications, Form J28-6177-3. IBM 7090/7094 IBSYS Operating System-Version 13; COBOL Language, Form C28-6391-0. (Note: For the purposes of this publication, differences are based on Version 5 of the 7090/7094 COBOL compiler.) This publication was prepared for production using an IBM computer to update the text and to control the page and line format. Pag
