Abstract for MVS Programming: Writing Transaction Programs for APPC/MVS
Purpose of this information
APPC/MVS is an implementation of IBM's Advanced Program-to-Program Communication (APPC) in the MVS operating system. APPC/MVS allows MVS application programs to communicate on a peer-to-peer basis with other application programs on the same z/OS system, different z/OS systems, or different operating systems including Microsoft Windows®, Sun Solaris, AIX, OS/400, OS/2, and VM in an SNA network. These communicating programs, known as transaction programs (TPs), together form cooperative processing applications that can exploit the strengths of different computer architectures. This document tells how to design and write APPC transaction programs to run on MVS.
In this document, the term APPC/MVS transaction program refers to a program scheduled by the APPC/MVS transaction scheduler (ASCH) or to any other program, running in an MVS address space, that uses APPC/MVS services. The term transaction is not restricted to programs scheduled by the APPC/MVS transaction scheduler, or to programs using APPC/MVS services. Note that APPC/MVS transaction programs are parts of cooperative processing applications and are distinct from, but coexistent and compatible with, CICS and IMS transaction processing applications.
Who should read this information
This document is for application programmers who design and write APPC/MVS transaction programs.
