   This publication gives the programmer the rules for
writing programs that are to be compiled by the IBM
DOS/VS COBOL and IBM Full American National Standard
COBOL compilers under the Disk Operating System. It is
meant to be used as a reference manual in the writing
of IBM Full American National Standard COBOL programs.

   COBOL (Cammon Business Oriented Language) is a
programming-language, similar to English, that is used
for commercial data processing. It was developed by
the Conference On DAta SYstems Languages (CODASYL).
The standard of-the-Ianguage is-American National
Standard COBOL, X3.23-1968, as approved by the American
National Standards Institute (ANSI). American National
Standard COBOL is compatible with, and identical to
international standarj ISO/R1989-1972, Programming
Language COBOL.

   IBM DOS/VS COBOL and IBM DOS Full American National
Standard COBOL, Version 3, which include all the
features of earlier versions, incorporate tne eight
processing modules defined in the highest level of the
American national stanjard.  These modules include:

     Nucleus
     Table Handling
     Sequential Access
     Random Access
     Sort
     Report Writer
     segmentation
     Library

A significant number of IBM extensions are implemented
as well; these extensions are printed on a shaded
background.
