Abstract for User’s Guide and Reference

This book is intended to help you compile and run programs written in the Restructured EXtended eXecutor (REXX) language. It describes how to use the:

IBM® Compiler for REXX on IBM Z® (referred to as the Compiler)
IBM Library for REXX on IBM Z (referred to as the Library)
IBM Library for REXX in REXX/VSE (also referred to as the Library)

It also describes how the Alternate Library can be used by software developers and users of z/OS® or z/VM® who do not have the IBM Library for REXX on IBM Z.

In addition to this, it describes the REXX Stream I/O function package and its usage for z/OS TSO/E.

It is assumed that you are familiar with the REXX language and with the operating system under which you compile or run your programs:

z/OS or OS/390® with Time Sharing Option Extensions (TSO/E)
CMS on Virtual Machine/Extended Architecture (VM/XA), Virtual Machine/Enterprise System Architecture (VM/ESA), or z/VM
Virtual Storage Extended/Enterprise System Architecture (VSE/ESA) with REXX/VSE

Some of the information applies to all systems: z/OS, z/VM, and VSE/ESA. Information that applies to only one system is indicated in the text.
