In the simplest case, writing to the MVS operator's console can
be accomplished by coding a WTO macro:
   WTO   'text'
where the text can be up to 120 characters, if memory serves me right.
There is a variety of optional parameters that affect message routing,
display attributes and such, which you can get out of the Supervisor
Services SPL.

If you want to write to a terminal (i.e. a TSO terminal), then you'll
need the TPUT macro - or the PUTLINE macro.  Both are documented in
the "Guide to Writing a Terminal Monitor Program or Command Processor".
I haven't used TPUT or PUTLINE in a long time and are sufficiently fuzzy
so that I won't post what I think are the requirements here.

Hope this helps.
