You're getting a Pterm if you call Pterm, and you're getting ^C if you
don't.  If you know you're calling Pterm, then call your clean-up
routine on your own and un-install it before you terminate.

Also un-install your terminate vector before you Pexec: you can tell
what the result of the Pexec was by the return code: -32L means the
child terminated with ^C.  Any other LONG negative value means the
Pexec failed, and any LONG positive value (i.e. (x & 0xffff0000) == 0)
means it called Pterm(x).

Please don't shoot words like "worthless" around unqualified.
