You didn't show the MVC, but when you said you prefer it to be
"close by", perhaps you meant that you would put it immediately
before or after the EX. Some like to keep it close without an
additional execution by coding:
EX R1,TEXT8000 MOVE IN ASCII NUMBERS
DATA LOCTR
TEXT8000 DS 0H
MVC 0(*-*,R6),B24AN FROM WORK TO OUTPUT ASCII
CODE LOCTR
