Scenario: "I have a COBOL server program and want to call this from the Integration Server."
Solution: Take an existing COBOL server program 
and generate the integration logic 
to call it from the Integration Server 
.
The COBOL server can reside in different operating systems and environments. Continue with the appropriate scenario:
z/OS - Choose your z/OS environment:
CICS - Choose your CICS calling convention:
DFHCOMMAREA (using CICS RPC Server)
DFHCOMMAREA (zero footprint using CICS ECI)
IMS - Choose your IMS environment:
UNIX (Micro Focus)
Windows (Micro Focus)
z/VSE - Choose your z/VSE environment:
CICS - Choose your CICS calling convention:
DFHCOMMAREA (using CICS RPC Server)
DFHCOMMAREA (zero footprint using CICS ECI)
