; NULUTERM.ASM	12/15/87
;
; For NULU.COM Version 1.52 (Do not use with prior versions.)
;
; The NULU.DOC contains the information to patch NULU.COM using DDT and
; the save command.  An easier way is to use this routine and then use
; MLOADxx.COM.	Set the various items as desired and assemble with ASM
; or MAC to obtain a .HEX file.  Then use MLOAD as follows:
;
;	MLOAD NEWFILE.COM=OLDFILE.COM,NULUTERM.HEX
