Relative Record Number in a Logical File

[TracyB250]

I have a program stuck in a loop that is using a logical. I'm wondering how I can find the record within the physical. I assume the I/O record and relative record number are referring to the logical and not the physical. Is there anyway to display a relative record number in a logical?


I/O ----Open--- Relative
Count Opt Shr-Nbr Record
2298 IO NO 22648

The RRN should be the RRN in the physical. I use that in these cases to find the exact record.

There's no RRN in a logical file. You can however get the physical RRN the logical is pointing to using the INFDS on the F-spec of the relevant logical file.
The RRN is a binary field pos 397-400 in the INFDS.
