HI, everybody. I'm here again.
I need to code a sort (dfsort or syncsort) in which I have 2 input files:
The main file and a file that will contain some updates.
If the update file is not empty I need to join both updating the main file.
If the update file is empty I'll have to write the output file from the main file just the way it is.
My first try was to include a IF/ENDIF to check if the update file is empty (it works) but I would like to code something inside the sort card.

Any help?

Post some sample inputs for both cases and show the output you want fro these sample inputs. Explain any processing "rules". Mention the dsorg and lrecl of all of the files.

In fact, what I need to know is how to check if my sortin file is empty or not. I know I can do that in JCL using IDCAMS, but I wanted to code that in my sort card.

I had seen those posts before. I was wondering if I could do that inside the sort card.

Sorry Dibakar, yes it's working but I didn't test it with the second file empty.
Now I did already and works fine.
Thanks a lot.
I think this conclude this post.
