Hi All,

Please find my requirement below.

I have one PS file (Recfm=FB,LrecL=80).It?s needs to be processed only if the file have at least one record say at step 2. If not I have to process the next step says Step3. So I need to check whether the file is empty or not at step1. Is possible to do this by using SORT?.

I know we can do it by file aid by checking the return code 8. But I am expecting millions of records in this file. So to improve the performance, I want to implement this by using SORT.

Could any one have a idea about this?

Thanks in advance,
Bharathiraj

Yes. The "Set RC=12 or RC=4 if file is empty, has more than n records, etc" Smart DFSORT Trick at:

http://www.ibm.com/servers/storage/support/software/sort/mvs/tricks/

shows how to do it.
