Considerations about REXX compiler
Workload Automation Programming Language is delivered in compiled form, which is not necessarily faster than interpreted REXX.
If you do not have a REXX compiler, you can use the Alternate REXX Library (SEAGALT) to run the compiled REXX. The alternative library transforms the compiled code into a form that is passed to the REXX interpreter for processing; this does not provide a performance improvement with respect to interpreted REXX.
If you have a REXX compiler, use the REXX Compiler Library (SEAGLPA) to see a significant performance improvement. This is recommended for high volume usage of Workload Automation Programming Language.
