Just one problem with that technique.

If you do this inside a subroutine (and I DO see people use STOP inside
subroutines all too often) you're locking into a legacy terminal
environment. 

Call that from e.g. .NET and the subroutine stops - but you don't get any
message back as to why. It's one more thing to refactor when changing front
end clients. 

For some interfaces it will even break the session.

So the lesson is - and I'm not suggesting that anyone on this list would do
this - don't use STOP (or even worse, ABORT) inside a subroutine. If you're
opening files inside a subroutine, just RETURN with a suitable error
message.
