Under MVS/TSO, quite often I use the results of SYSVAR('SYSNEST') to
determine if my code is running at the top level, or has been called from
another REXX exec. I use this knowledge to build utility routines that I
can either call directly (and have them display results) or call from
another routine in which case the results are returned as a character string
to the calling exec. Is there an equivalent facility available under ooRexx
that I can use to determine if I'm running at the top level or not?
Thanks in advance,
Robert

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
