Dear ADSMr's

We are trying to use select to extract information from our ADSM server. The 
commands do not function as expected.
Can anybody tell me where I can find the subset of SQL92/93 commands for ADSM. 
Can we select files with certain extensions and how much space they occupy 
using the select command ?
Does SAMS vantage give that functionality ?
I like to delete the files that are not required and try to ascertain how much 
space is used up legitimately by the users.

Regards
