There are different styles (interface types) for calling a COBOL server.
It is important to know the interface type of your COBOL server.
If you are unsure, consult a COBOL CICS specialist or see
description of interface type in the IDL Extractor for COBOL documentation for details and examples:
DFHCOMMAREA Calling Convention |
DFHCOMMAREA Large Buffer Interface.
When you are sure which programing style you are using, continue with the appropriate scenario:
DFHCOMMAREA (using RPC Server for CICS)
DFHCOMMAREA (zero footprint using CICS ECI)
