RE: Exiting a sub procedure

I'd advice to re-engineer your procedure, this is a use-case for one of
my favourite stick-horses: only ever use one return per procedure. It
might result in one or more if-statements, but in that case you could
also write one subprocedure which determines which case to use and write
a dedicated subprocedure only handling one case. Clean, concise, easily
extendable and maintainable.

You could write a subroutine within the subprocedure to prevent
duplicate code (exsr handle-false or so), but if the handling code is
less than 3 lines that might be construed as overkill (however, in that
case bring forward that maintenance needs only be done in one place).

I don't know why debug ends up at the end-line of the subprocedure, I
have my suspicions (some hidden return-to-the-calling-opcode-opcode) but
I don't know.

My 2 eurocents,
Cor

Subject: Exiting a sub procedure

Hello,

I'll be surprised if there's anything but NO to this question, but

I've

learned on this list that if you don't ask you don't learn so here

goes

anyway.

I have a subprocedure with many RETURN *OFF coded within. Now I need

to

add some code in the case of it returning *OFF. I think I have to copy
this code before every RETURN *OFF. Is there anything that let's me
call another procedure on exiting this subprocedure? I just wondered
when debugging and noticing that RETURN *OFF seems to step to the line
at the end of the sub procedure.
I don't want this code done by the calling procedures as they are many
and external.

Thanks.
