I've got a request to not send a file via ftp in a jobstream if it is empty, but to skip the send.

I have an assembler program that reads the catalog for VSAM files and works, but it doesn't work for a SAM file.

Where can I find record count for a SAM file so that I can set a CC to skip the ftp step ?

Or - is there a preferred method in MVS to accomplish this ?

stansaraczewski,

Look at the smart DFSORT trick "Set RC=12 or RC=4 if file is empty, has more than n records, etc" here

Perhaps this may work with another sort product - I don't think we are using dfsort.

Thank you for the idea.

IDCAMS PRINT will do it, print one record and if the record is printed you get RC0, if no records to print RC4.
