CICS mapping to the APPC architecture

This appendix shows how the APPC programming language is implemented by CICS®.

The APPC programming language is described in the SNA publication, Transaction Programmer's Reference Manual for LU Type 6.2) This appendix contains the following topics:

Supported option sets.
This is a table showing which APPC option sets are supported by CICS and which are not.
CICS implementation of control operator verbs.
This section describes how CICS implements the APPC control operator verbs. It includes tables showing how these verbs map to CICS commands.
CICS deviations from APPC architecture.
This section describes the way in which the CICS implementation of APPC differs from the architecture described in the Format and Protocol Reference Manual: Architecture Logic for LU Type 6.2.

For information on how the CICS application programming interface for basic and unmapped conversations maps to the APPC verbs, see the CICS Distributed Transaction Programming Guide.
