Course description
REXX is a powerful language that is widely used on MVS. It is also the programming language for IBM Tivoli AF/OPERATOR, OMEGACENTER Gateway, and AF/REMOTE products. This course will introduce students to REXX and teach them how to write REXX programs in the MVS environment through a series of lectures and hands-on lab exercises. Beginning with simple programs, the course advances through more complex topics, including file I/O, stem variables, REXX functions, writing subroutines, and debugging.
