Thanks for info... will be chattin' in the New Year... have included part
of macro re NUL appended string...


            shr   cx, 1         ;divide by 2 to move words
       rep  movsw               ;until cx is 0
            jnc   @f            ;if odd num of bytes in string, carry flag set
            movsb               ;move last byte if odd number
@@:         mov   es:[di], cl   ;add terminating NUL es:ax points to buff80
            mov   ofset, ax
            mov   ax, es
            mov   segmnt, ax    ;exit with segmnt:ofset pointing buff80

ofset and segmnt are macro args...  This is approach I use for NUL
termination of BASIC strings... Macro can be called with ds:dx and returns
ds as segmnt and dx as ofset...
