The IBM Rexx compiler at least does compile your script to the internal tokenized format that the Rexx interpreter actually executes, so running a "compiled" script avoids the overhead of translation to that internal format.
That isn't a lot of help for single-level scripts, but if you have a Rexx "main" program that calls other (external) Rexx programs in loops executed many times then the time savings can add up. However, analyzing where and why a Rexx script takes a lot of time may prove to be a more fruitful way to speed up overlong processes. Like any other "save more time" effort, logic analysis and adjustment frequently provide better results than just using a compiler can provide. Peter -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Gadi Ben-Avi Sent: Thursday, January 28, 2021 12:30 PM To: [email protected] Subject: REXX Compiler Hi, I was asked to investigate a REXX compiler. I found the IBM REXX Compiler and a product called eXtended Compiler for REXX from a company called improvIT Software Innovations?. The main goal is to make REXX programs run faster. Do these products help with that, or are they just a way to create a load module that 'hides' the source code?
