Stop and return to caller [message #71804]

Hi,

I have a small question for which I haven't found a pleasant solution.
I am looking for a way to stop the execution of a procedure and return
to the level of the programme that called that procedure. Currently I
have something like this:

pro my_pro,a,b
on_error,2

c = a + b
if (c lt 0) then message,'c < 0! Stopping...'
end

It works, but the main problem is that since it is generated as an
error, it outputs all the calling stack with line numbers and so on. I
would like to do something cleaner, like for instance the "stop"
procedure which outputs only the current position in the execution.

Thanks a lot in advance,
