The current PSP is stored in a DOS global variable and presumably you could
access its contents directly;  of course this technique is highly dependent
on the DOS version.  I don't understand the reluctance to use the DOS
functions to retrieve this value.  The PSP manipulation services do no stack
switching and are always safe (if properly used) -- at least in all DOS 3.1
and above.  Don't know about DOS 4.0 and 4.0.1.
