Is there a way, via JCL, to identify that a given input (QSAM) file is empty?

Only if you consider running a utility against it to open the file as "via JCL".......

If by "identify" you mean pass back a non-zero return code, you can use the technique described in the "Set RC=12 or RC=4 if file is empty, has more than n records, etc" Smart DFSORT Trick at:

If that's not what you mean by "identify", then please explain what you do mean.
