INT 15 - TopViewTopView, DESQview, TaskView, OmniView, other compatibles - "GETMEM" - ALLOCATE "SYSTEM" MEMORY
	AX = 1001h
	BX = number of bytes to allocate
Return: ES:DI -> block of memory or 0000h:0000h (DV v2.26+)
	AX = status (DV v2.42)
	    0000h successful
	    0001h failed
Note:	use SETERROR (AX=DE15h) to avoid a user prompt if there is insufficient
	  common memory.  Under DV v2.42, this call never generates a user
	  prompt regardless of the SETERROR value; instead, it always returns
	  AX=0001h and ES:DI=0000h:0000h if out of memory
