INT E0 - REAL/32 - "P_TERMCPM" - TERMINATE CALLING PROCESS

	CL = 00h
Return: AX = error code
	    FFFFh on failure
	may destroy SI,DI???
Program: REAL/32 is the descendant of IMS Multiuser DOS, which in turn is
	  derived from DR Multiuser DOS and its predecessors (Concurrent DOS,
	  etc.)
Notes:	sets the exit code (ERRORLEVEL) to 00h
	INT E0h is officially reserved for Digital Research by Intel.
	Apparently some Borland products also used this interrupt, which forced
	  Digital Research to indirect calls through other interrupt entry
	  points.
	This is also supported by IMS Multiuser DOS and IMS REAL/32.
