RE: Stopping processing with using a bunch of if statements

My subject line should have read ...WITHOUT using a bunch of if statements. Oops.

If there is an error in Procedure2, I do not want Procedure3 or Procedure4 to run. Won't the if that you provided execute all three and then check the status of the IF?

How about something like this...

Have each procedure return a success indicator where *on = success, then

Begin Procedure1

if Procedure2()
and Procedure3()
and Procedure4() ;
clear Errorfound ;
else;
Errorfound = *on;
return;
endif;

Mainline can then test for Errorfound that was set by the procedures.

I have an RPGLE program that calls a number of procedures. If it is
in a procedure and it detects an error, I want it to stop processing
and exit back to the main procedure where the initial screen is
displayed to inform the user of the error. I do not want the program
to abend. Is there a way do to this without placing an if statement
after each procedure? That could get really ugly and it would
probably be easy to miss one because not all procedures can encounter
an error.
