Can you imagine if everyone did this to get around giving up control of the
processor <sigh>
This is not a solution. It might work, but not a solution. Can you
describe more what you are trying to do??

Did somebody rewrite the Operating System while I wasn't
looking? When you issue a valid WTOR, control is returned to
your task (subject to normal dispatching considerations). The
communications task will asynchronously issue the WTOR request
to the appropriate console.

No, but I think you're confused. Nobody is forcing you to wait
for a reply unless your program has a WAIT SVC. If you want to
keep running, don't WAIT.
But if your intention is to keep running normally, with a WTOR
response being optional, you should look at the MODIFY facility,
that allows the operators to issue a command to your task
without tying up a response number.
