setsite question

CL 6.0.2 on AIX

I’ve successfully created multiple sites and have things processing thanks to Jim K.  

I’ve checked multiple threads here on how to get the ‘setsite’ to work called from a script. [My head is spinning from all the reading!]  We have a current archiving script that does cycle-saves and moves the current day file to an archive directory.  With multiple sites, I need to be able to set the site to the various ones to correctly archive those files.

So..any ideas?  

Thanks.
