Re: RRN of an IP record

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
