Hi Ram,

You can use IDCAMS for the VSAM files or you check in the
DSLIST (3.4 OPT) ,%USED will be 0 for empty files.

You could use DFSORT's ICETOOL to do that as described in this Smart DFSORT Trick:

Hi Frank & Ram,

this is the outline..how IDCAMS can be used:

Step 1: copy the file to a temp file using IDCAMS utility
If file empty this step may throw a RC 08,
Set MAXCC = 04, if it greater than 00.

Step 2: Check the condition, if the RC of previous step is NOT equal to 00, bypass the step.

Thanks.
