REXX programs tend to be shorter and easier to follow than programs written in other languages, making it ideal for both new and experienced IBM Z programmers.
REXX’s high level simplicity, strong parsing, 'naturalness' and interpretive support offers developers a reduced development cycle and excellent source-level interactive debugging.
Both the REXX Library and the REXX compiler provide integrated error checking and data during debugging, which can make your systems management more efficient.
