When you refer to "offset tstmsg" the assembler gives you the offset from the beginning of the segment in which tstmsg is defined. Unfortunately, the DS register points to the beginning of DGROUP, not the beginning of your segment, so the offset is not what you want. Try this to get the offset you want: mov dx,offset dgroup:tstmsg -- John R.
