[Zope] Inserting data into a catalog with dtml

I'm trying to pull data from an odbc database and insert it into a zcatalog. For reasons I won't go into, I need to use DTML to accomplish this. I'm able to pull the data using ZSQL, but can't figure out how to drop it into the catalog with a DTML command. Any tips? TIA, Aaron abg@comco-inc.com
