I took a closer look at that section in the reference, and it DOES
explicitly state
"if you are doing blocked input on a data base file, the relative record
number and the key value in the data base feedback section are updated:
- On every input/output operation, if a POST for any file with
factor 1 blank has not been specified anywhere in your program.
- Only after a POST for the file, if a POST for any file with
factor 1 blank has been specified anywhere in your program."

I skipped right over that section when I looked yesterday...

Thanks for the clarification.
Eric

Eric,

I think you're confusing ILE RPG with RPG/400. This is a direct
copy/paste from the ILE RPG programmer's guide:

The input/output and device-specific feedback of the file
information
data structure are not updated after each read or write (except for
the RRN and Key information on block reads) for files in which the
records are blocked and unblocked by the RPG compiler.

Note the part that says "except RRN". RRN *is* updated on every read.

Not by default, IIRC...

Chapter 5 in the ILERPG reference has a section named "Blocking
Considerations" discusses this in detail.

Short answer: You must use the POST opcode to force the INFDS to
update....

Hth,
Eric
