How to identify the difference between IBM REXX code and RLX REXX code.
Release : 20.1
Running a REXX source code search/scan using the keyword "RLX" should yield a fairly complete list of REXX programs using the RLX extensions.
Also searching using a keyword such as SDK to identify RLX for VSAM.
Unfortunately there is not a single search keyword to identify all possible API calls.
