>>I verified for all non-VSAM datasets (FB, VB, FBA etc.) and it is working fine.<<
It works ok on my side too, in the sense that there are no error messages. However, when I check to see if the second append to a dataset worked, it looks like the dataset was overridden, rather than appended to.

Didn't use IDCAMS yet, I thought REPRO would be more direct.
