REXX for CICS Transaction Server

REXX/CICS® or REXX for CICS Transaction Server provides a native REXX-based language environment for application development, customization, protoyping and procedures, along with associated runtime features.

REXX/CICS runs under all supported releases of CICS Transaction Server.

This reference describes the REXX for CICS Interpreter (referred to from now on as the interpreter or language processor) and the REstructured eXtended eXecutor (called REXX) language. This reference is intended for experienced programmers, particularly those who have used a block-structured, high-level language (for example, PL/I, Algol, or Pascal).

Descriptions include the use and syntax of the language and how the language processor interprets the language while a program is running under the REXX/CICS interpreter. The reference also describes:

Programming services that let you interface with REXX and the language processor.
Customizing services that let you customize REXX processing and how the language processor accesses and uses system services, such as storage and I/O requests.
