CICS conversion considerations

To run COBOL V5 and later programs under CICS®, you need to be familiar with the required CSD and DFHRPL updates. You should also be familiar with compiler options for CICS. Finally, you may want to migrate to the integrated CICS translator.

Consider the following topics:

• CSD setup differences with Enterprise COBOL V5 and V6
• DFHRPL setup differences with Enterprise COBOL V5 and V6
• Compiler options for programs that run under CICS
• Migrating from the separate CICS translator to the integrated translator
• Static calls from COBOL V5 or V6 programs to VS COBOL II programs under CICS

OS/VS COBOL restriction

OS/VS COBOL programs no longer run under CICS. Any OS/VS COBOL programs to be run under CICS must be upgraded to Enterprise COBOL.
