To extend your punch suggestion a bit, rather than saving the status of the
punch and using it to test the user, would it be more elegant to define a
"new" punch at another address, spool that one, then detach it?
Such as:
Cp define pun 01d
Cp spool 01d to foobar
HCPCSP053E FOOBAR not in CP directory
Cp detach 01d
This removes the need for saving and restoring the original punch's status,
and shortens the code path considerably. It's a virtual system, so let's
make use of as much of it as we can... :-)
