REXX error handling

Several types of errors are associated with REXX run-time interface.

Translation errors
Errors that occur while REXX is trying to interpret a CICSPlex® SM API command result in a REXX return code.
Run-time errors
Errors that occur while CICSPlex SM is trying to process an API command are reported by the RESPONSE and REASON values for the command.
TPARSE and TBUILD errors
The results of a TPARSE or TBUILD command are returned by the STATUS option, which is a required option on those commands. The STATUS option serves a similar purpose to the RESPONSE and REASON options on other API commands.
Messages
Many of the error conditions you might encounter when using the REXX run-time interface are accompanied by messages that describe the error.
EYU_TRACE data
The run-time interface creates a REXX stem variable called EYU_TRACE anytime an error occurs that warrants tracing.
