Questions on JCASscript clipsetretention

Hi,

I working with JCASscript trying modify the retention date of a clip to set up some test cases.   I'm new to JCASscript, but I think I'm using the correct steps.  After opening a pool and querying the clip, I run clipopen using a clip id from the query.  clipinfo shows the retention seconds as 0.   I issue clipsetretention 10000.  Issuing a clipinfo command displays the retention seconds as 10000.  If I close the clip (clipclose) and then reopen with clipopen, clipinfo shows the retention seconds as 0 again.

So, I'm trying to figure out what is going on.  Am I supposed to be able to set the retention date for an existing clip?  If so, why is it showing me it's changed when it really didn't?  Any help would be appreciated.

Thanks,
