[asrpg400]

Hello Everybody

Can any one of u tell me that how to get Relative Record Number of a particular field, in a rpgle pgm.

I am reading a PF in my PGm and then i had to use chain to go back to certain position and read again. So how can i determine the RRN while i make a READ.

Thanks

Getting RRN from a file

You must attach a data structure to the file.

fLOCKFILE  UF   E             DISK    INFDS(INFDS)

and look here for the wealth of information available

Now the RRN number would only help if you were reading a physical file that is not keyed.

If the file is keyed you really should use keylist.


good luck
