The OS/2 Procedures Language 2/REXX


(C) Copyright IBM Corp. 1987, 1994.  All Rights Reserved. 
The OS/2* Procedures Language 2/REXX (referred to as REXX for the rest of 
this information) is designated as the Systems Application Architecture* 
Procedures Language for the Office Vision family of products and the OS/2 
operating system.  It was designed to make programming easier to write and 
debug.  High-quality programming can now be achieved using common English 
words in a natural syntax flow that both beginning and experienced 
programmers can understand. 
REXX uses a few powerful, general-purpose programming functions and common 
arithmetical abilities, as well as OS/2 commands, within a simple 
framework.  Existing batch files can be converted to REXX procedures, with 
more power and function. 
REXX files only operate in OS/2 sessions, must have a file name extension 
of .CMD, and must start with a comment line (/*....*/).  As in batch 
files, it is not necessary to type the .CMD extension to start a REXX 
procedure. 
This Information: 
This online REXX information is designed to acquaint you with the REXX 
language, show you some of its features and capabilities, and give you a 
 basic understanding of how it works.  The sections from "Getting 
Started.." to "PMREXX" are written as an overview, stressing general 
concept information, while the sections on "Instructions" and "Functions" 
include specific information about all of the instructions and functions 
that are part of REXX. For more complete and detailed information about 
REXX, see the OS/2 Procedures Language 2/REXX Reference or User's Guide.
