Programs invoked by REXX (TSO)

Some programs, particularly REXX function packages, need environmental setup for debugging because they are invoked by the REXX interpreter. There are other special considerations that apply to any program invoked by REXX.

REXX functions must return an EVALBLOK. If you quit from IDF while in the middle of a REXX function, an error message is issued by the REXX interpreter, and you may have to LOGOFF and then LOGON to TSO again.

There is no practical way for IDF to stop this.
