REXX in OS/390-z/OS & VM (and on PC), from Michel Castelein (in Europe)

REXX is a programming language intensively used in the mainframe world to write scripts.

But REXX is also available on many other platforms.

Therefore the course covers the use of REXX in z/OS & z/VM, and on PC.

This 5-day course combines theory and practice.

Although REXX is very powerful, you can paradoxically also attend this course to learn very first programming language.

Classic REXX tutorial/reference, by Keith Watts


Rexx provides exceptional capabilities for processing character text strings.

All program values are strings.

Some string values can be processed in arithmetic operations.

String values can contain arbitrary byte values including binary zeroes.

The powerful parse instruction provides many ways for extracting string segments to variables.

Rexx programs are usually processed immediately by an interpreter, rather than a compile/link/execute sequence.

Rexx is very helpful for developing small programs that perform various text file transformations.
