Why won't it matter? if readp encountered EOF (top of the file), the cursor
is lost. The READE will fail.

No, I said readp not readpe. readp is not keyed so it just moves up to the
record above the current. The only way you could get EOF on readp is if you
were already on the first record of the file. In that case, it wouldn't
matter.

Subject: Re: Re-READ the current record
yes, that is what I'm afraid of and that is what I come up with. It is
quite ugly. It gets even uglier because I'll also have to consider readp(n)
could encounter %eof condition. From what I know, when %eof is encountered,
the cursor is lost. So, I'll have to position it to the top of the file and
do a reade. what in the world...

you will have to do a readp(n) to move the cursor up one, and then reade.

Subject: Re: Re-READ the current record
two problems with this:
1) reade is usually performed in a loop and I need the record to know if I
need to perform the update.
2) setll/chain won't work if the file that it is looping thru does not have
a unique key.

Setll (mykey1) MYFILE;
If %Equal(MYFILE) and needUpdated();
//Read with Lock
reade (mykey1) MYFILE;
Endif;

Objet : Re-READ the current record
Is there a way to re-READ the current record (without using CHAIN) that the
RPG program has just READ?
For example:
reade(n) (mykey1) MYFILE; //read it with no lock
if not %eof() and needUpdated();
==> Need to re-read with locked how???
