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 zSeries (referred to as the Compiler)

• IBM Library for REXX on zSeries (referred to as the Library)

• IBM Library for REXX in REXX/VSE (also referred to as the Library)

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(TM)) with REXX/VSE
