The REXX Files

The Truth about REXX is out there. And in here.

REXX is a scripting language found in many platforms, including MVS, OS/390, Z/OS, CMS, VSE, CICS, Windows, Unix, Linux, AS/400, and others.
REXX is generally interpreted, which makes development easy, but gives a performance penalty.
Compilers are available for REXX.
REXX has all the facilities of a complete programming language.
REXX is particularly good for processing data strings.
REXX is not datatyped: all variables may contain any type of data.
REXX data is either character (string) data or numeric.
There is only one type of numeric data in REXX.
Numeric data in REXX is processed internally in floating decimal format, so conversion does not take place.
There is information here about REXX books and programming.

The REXX Language on TSO

By Gabriel F. Gargiulo

Available at Amazon.com and other booksellers. (Published August 2012). REXX for mainframe IBM MVS, OS/390, Z/OS, TSO. Since there was so much demand for my TSO REXX book, "REXX in the TSO Environment," I decided to write a new one. This book will teach you the REXX language on TSO. If you need REXX for another operating system, you can learn REXX with this book because the differences are minor.
