Hello! I see no one, outside of myself has thought it should also be Anarchist Standard Time.

Re: How to determine if running as a multitasking CMS app
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.
