RE: Cycle Processing vs. Doing it my way -- RPG400-L

BUZZ!  I poop on the do-do's.

Why not...

Key     chain(e)        file_name
        Select
        when            %status(file_name) = xxxxx      Not found
        when            %status(file_name) = yyyyy      Locked
        other
        (good read logic goes here)
        endsl

No GOTO and no misuse of DO.  //Besides, this is what you mean!//

Regarding "F" for the use of a GOTO: if you can justify the use of a GOTO
(program readability, logic flow, etc.), you should get an "A".

Amen
I always use Do loops to avoid using a goto.  I've always been taught that
goto's were bad.
(In school we got an automatic F for a project that used a "goto") although
there are times
where I wished I could use them, I force myself not to.  I know we all have
programming
standards,  I prefer using a "Do"  and on a specified condition you can
LEAVE the Do
and continue processing. Ex.

                                    Do
                                    Read            Custmast
                                    If                     NOT % FOUND
                                    LEAVE
                                    Endif

                           continue processing

                                   EndDo

Looks much cleaner than using a goto, make it a lot easier to maintain
also.
Your not having to look for tags and Gotos everywhere. (I have seen and
used both) and yes I think gotos create spaghetti code, it will have you
mind
wrapped around in circles trying to find out how the cycle works.
This is Just my 2 cents.

And what is wrong with LEAVE? It hardly creates spaghetti code as the
program flow is always in the one direction. I like to refer to a LEAVE as
a structured GOTO!!!!!
