This publication gives the programmer the rules for
writing programs that are to be compiled by the IBM Full

Operating System. It is meant to be used as a reference
manual in the writing of IBM American National Standard

COBOL (Cammon Business Oriented Language) is a
programming-language, similar to English, that is used for
commercial data processing. It was developed by the

IBM as Full American National Standard COBOL is
designed according to the specifications of the following
industry standards:
* The highest level of American National Standard
COBOL, X3.23-1968, including all eight modules:

Random Access, Sort, Report Writer, Segmentation,
and Library.
* International Standard ISO/R 1989-1972 Programming
