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.
