REXX for TSO

REXX for TSO is used in an environment more or less dedicated to system administrators and program developers. It is not generally used as a programming environment by end-users and so REXX tended to be used to make system utilities more user-friendly and as an application "wrapper" for end-users. REXX procedures that I wrote on VM have been successfully ported to the TSO environment - the REXX code remaining the same but system I/O calls being adapted for TSO.

The following publications are available for REXX on IBM mainframe systems:

• TSO/E Version 2 Procedures Language MVS/REXX, SC28-1883
• VM/XA SP Interpreter: Reference, SC23-0374
• VM/ESA Release 2 REXX/VM: Reference, SC24-5466
• IBM VSE/ESA REXX/VSE Reference, SC33-6529, is interesting for experienced programmers, particularly those who have used a structured high-level language. They list the REXX messages and describes instructions, functions, debugging aids, and parsing.
• Systems Application Architecture Common Programming Interface: REXX Level 2 Reference, SC24-5549, describes the SAA REXX interface.
