The problem is that I may eventually need to do a ThreadCreate (note Multitasking CMS call, not POSIX pthread_create) or EventTrap call, but not initially. It seemed pretty ugly to me to have to create a thread just to decide if I was running as a true MT CMS app or not. Not providing a call to determine this seems to have been an oversight (along with having VMPROCESSEND events keyed on process name when there's no way to retrieve a process ID from a process name - but I digress).
Thanks to everyone for the ideas provided - I think I'll stick to running the chain of PSDs.

Unfortunately I don't understand the underlying problem. If I wanted to know if pthread_create was going to work, I would issue it and remember the answer, so that I could fallback to Plan B. But since that's the obvious answer, I figured that wasn't the problem. Alan Altmark z/VM Development IBM Endicott
