Hi Mahesh, If you do a YDSPLICPRD you will get a list of your licensed products. This should show you the release. Now, it does get interesting for 8.5, as 8.5 uses the same licensing as 8.1, so you then have to look at the YSY2LIB level from the YDSPMDLVAL command, option 9. If you are at 8.5, then that value will be 1351. Crispin.
