You can get the RRN of a PF using an INFDS.  Do a search in your
softcopy library (or on the web) in the RPG Reference manual for
"INFDS" for details.

If you use this approach, make sure that your RPG program is not
performing "blocking" on the file.  Blocking will cause the RRN's
in the INFDS to be updated only once per block read, instead of
on every record.

You may also want to use caution that another job can't update this
file at the same time.   A simple ALCOBJ with a MONMSG in a CL program
should accomplish this nicely.   I'm assuming that you don't want
other people to be changing the file at the same time...  If thats
not the case, ignore this remark :)

Hope that helps...
