From the ILE RPG Language Reference:
Under the READE op code: " If a READE operation is successful, the file
is positioned at the next record that satisfies the operation."
This means that when you issue the READPE you will get the record you
just read by the READE not the prior record.
READE gets record 1, file positioned before record2,
READE gets record 2, file positioned before record3,
READPE gets record2, file positioned before record2,
READPE gets record1, file positioned before record1,
This functionality is independent of whether you use a data structure on
the read.

Subject: Another data structure issue
Is there any issues with using a data structure with a READPE?
I've run into a situation where on the readPE its not reading the first
record.
IE: I loop through the file for a key, it finds the first record and
then
reads the second record, I then execute a READPE with the same key but
the
file pointer never moves back.
