          INT 21,50 - Set Current Process ID  (Undocumented DOS 2.x)


       AH = 50h
       BX = process ID number (process PSP segment address)


       returns nothing


       - the process ID number is actually the segment address of a
         program's PSP.  This is useful for TSR's to access their own
         file handle table inside their PSP.
       - this function cannot be called while in an INT 28 handler in
         DOS 2.x unless the critical error flag is set or stack corruption
         will occur
       - safe in DOS 3.x INT 28 handlers since they use a different stack
         by default
       - available in OS/2 compatibility box
       - see  INT 21,51   INT 21,62
