RE: How do I retrieve the RRN of a PF or LF in a RPG program.

Thanks, Mark

That does give me what I need. Its going to be a slog to parse out the values in rpg/400.

Darryl,

If the only thing you "need" the RRN for is to find out the job holding the lock, I think you may be trying to do this "the hard way"... See this article:

Hope that helps,

Thanks all so far.

The program is a RPG/400 and I cannot find the maximum length of the data structure. The positions Paul gave return the value 1077952576.

I should be seeing 94.

Maybe what I want to do is not doable. Unfortunately I cannot upgrade the program to ILE. So here is my problem. I read file in a loop simply using READ. The first record is locked to another job. I need to be able to get the RRN of the locked record so that I can retrieve the job details locking the record and end the job.

I have monitored for the error indicator and that is working. My problem is getting the RRN.

Thanks
