If you're running under TSO, won't the length of the PLIST tell you
whether you were invoked directly by a command? Anything other than a
CPPL means a call.
The original TMP ran unauthorized, including the TMP in SVS and OS/VS2
(MVS); if you look at the COOKIE command, you will see that a nested
TMP worked just fine. As I recall, it was the TSO Command Package[1]
that added the parallel TMP structure that required authorization.
