I did that until recently (like a year ago), when somebody convinced me it was
evil. Well, convinced me enough to stop; I sort of agree that if you can't
handle it, don't be doin' no assembler, but I still stopped. I used to use this
format:
TM FLAG,BIT
JO *+8
L R1,WHATEVER
*+8 DS 0H
That made it clear where it was going and thus made it harder (I think) to
insert stuff blindly, while not encouraging anyone else to branch there :)
