Under z/OS, a COBOL server can be called in different environments:

	Extract the interface of the COBOL server program. See Using the IDL Extractor for COBOL - Overview.
	Generate REST resources, connection and adapter services in Integration Server.
	Execute the call from the REST client to the COBOL server program.

Continue with the appropriate scenario:

• CICS - Choose your CICS calling convention:

  • DFHCOMMAREA (using RPC Server for CICS)

  • DFHCOMMAREA (zero footprint using CICS ECI)

  • Large Buffer

  • Channel Container

• Batch

• IMS - Choose your IMS environment:

  • MPP - online transactions (zero footprint using IMS Connect)

  • BMP - batch processing (using RPC Server for IMS)
