RE: %EOF

["Stone, Brad V (TC OASIS)" <bvstone@xxxxxxxxxxxxxx>]

Dale,

First clue.  DOU vs. DOW.
Second clue.  Multiple exit points to a loop.  (Any comp sci book will tell
you this is a no-no)

Again, in the end it's simply a matter of preference.  Structure has nothing
to do with it.  I was simply pointing out a method that may solve the
problem, and including the gererally accepted method of using a priming
read.

Any more responses or anyone who wants to disagree, feel free but take it
off line.

Brad,

>>Key        SETLL    Filename
Key        READE    Filename

            DOW   not %EOF(Filename)

        (do some code here)
Key        READE    Filename
            Enddo

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

IMHO: No, no, no, no!!!!  How is that more "structurally correct" than:

Key      Setll     Filename
         DoU       %EoF
Key      ReadE     Filename
         If        not %EoF
.. do some code here ...
         EndIf
         EndDo

or maybe even:

Key      Setll     Filename
         DoU       %EoF
Key      ReadE     Filename
         If        %EoF
         Leave
         EndIf
.. do some code here ...
         EndDo

I would always rather have one READE in a loop than two.

Back to the original poster's question, though; it sounds like a bug.  Are
you
up to date on PTFs?  Might be worth checking.
