Building Enterprise REXX Automation: Scripting TSO/E, ISPF Panels, and SDSF Job Parsing
REXX is the scripting powerhouse of z/OS. Learn how to write robust REXX scripts that interact with TSO/E, display custom ISPF panels, and programmatically parse SDSF batch job spool logs to trap production errors automatically without expensive 3rd party tools.

Architectural Prevention & Performance Tuning Checklist
- Use REXX stem variables (`STEM.0`) for clean memory cleanup when processing large lists.
- Always include `SIGNAL ON SYNTAX` and `SIGNAL ON ERROR` for resilient enterprise error handling.
- Combine REXX with z/OS UNIX `cURL` commands to post incident alerts directly into Slack or Microsoft Teams.
- Store shared enterprise REXX utilities in common `SYSPROC` or `SYSEXEC` concatenations.
