Relative Record Number in a Logical File

Relative Record Number in a Logical File

Relative Record Number in a Logical File

(OP)
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
    

RE: Relative Record Number in a Logical File

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

RE: Relative Record Number in a Logical File

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.
