RE: %EOF

[bellis@xxxxxxxxxxxx]

I would like to see an example where you would need to use a GOTO statement as
mentioned below.
I agree that the format using a priming read and DOW is much more structurally
correct.
I think it is much easier to read the DOW loop when there is a lot of code in
the middle. It is much more
difficult trying to determine where the Leave statment is going to take you.
By the way, you should never have to use a GOTO in an RPG program !!!

Key        SETLL    Filename
Key        READE    Filename

            DOW   not %EOF(Filename)

        (do some code here)
Key        READE    Filename
            Enddo






Have you ever had to skip a record and tried using "ITER" in your loop?  I
also use the:
"IF EOF LEAVE"  after the read at the top of the loop.  It is easier when
you have a lot of code within the loop to ITER than to skip with an IF/ENDIF
or, should I dare say, GOTO.  Agreed that having the initial read prior to
the loop and at the bottom of the loop gives the loop control to the loop
definition, but I like ITER/LEAVE myself.

 Change it to this...  More structurally correct as well.

Has anyone here had problems associating a filename with the %EOF bif?  I've
been experiencing intermittent problems which seem to be occuring only in
service programs.  When I pull the code out to a separate program to try to
isolate it, it works fine (naturally).  Here's what I'm seeing:

Key        SETLL    Filename

            DOU    %EOF(Filename)
Key        READE    Filename

             If          %EOF(Filename)
                Leave
            Endif

            If            %EOF
                Leave
            Endif

        (do some code here)
            Enddo

When executing this code against an empty file, the first LEAVE does not
execute, but the second one does.  When I put a numeric indicator on the
READE, it comes on normally.  This is the entire code in a procedure in a
service program (second LEAVE was added in testing) and, as I say, when
pulled out into a test program it works fine.  Does anyone know how the
filename gets associated with the %EOF and what might disrupt that
association?  There is no code between the READE and the first IF.  I'm on
V4R3.
