I'm not familiar with BPX1EXM but it must be more difficult than calling an APF 
AC(1) module. Maybe some sort of RACF auth for each program? Something has to 
be protecting this otherwise the auditors would be all over it.

I believe the TSO alternative is TSO CALL. Maybe one of the REXX commands (e.g. 
LINKMVS) provides this functionality.

This is a fully secured API. Very few AUTHPGM's are defined.  I suspect the 
documentation is buried where experts most likely will find it. No sense in 
encouraging it's use by people who don't fully understand it.
