COBOL reserved word comparison
The following table shows differences in reserved words between OS/VS COBOL, VS COBOL II, IBM® COBOL, and Enterprise COBOL.
Information about source language comparison can be found in:
Key:
- X
- The word is reserved in the product.
- -
- The word is not reserved in the product. (This includes obsolete reserved words that are no longer flagged.)
- CDW
- The word is an Enterprise COBOL compiler directing statement. If used as a user-defined word, it is flagged with a severe message.
- RFD
- The word is reserved for future development. If used, it is flagged with an informational message.
- UNS
- The word is a 85 COBOL Standard reserved word for a feature not supported by this compiler. For some of these words, the feature is supported by the Report Writer Precompiler. If used in a program, it is recognized as a reserved word and flagged with a severe message.
