Chapter 2: Compatibility Directives

This COBOL system provides compatibility with:

Data General Interactive COBOL rev 1.30
Ryan-McFarland COBOL V2.0

Compatibility is provided through the use of Compiler directives.

Net Express:
See the Compiler Directives help for full details of all Compiler directives, and the features they enable.

Server Express:
See your Server Express User Guide for full details of all Compiler directives, and the features they enable.

2.2 RM

Specifies that words reserved in Ryan-McFarland COBOL V2.0 are to be regarded as reserved words, and changes the behavior of certain features to be compatible with that COBOL system.

>>------.---------RM--"ANSI"--.-----><

NORM sets SEQUENTIAL"RECORD", TRUNC"ANSI", NOOLDINDEX, OPTIONAL-FILE, NORETRYLOCK and ALIGN"8" immediately.

Comments:

With the ANSI parameter these features behave as they do when a program is compiled in that COBOL system with the ANSI switch set. See your Language Reference.
