Connecting to a Datacom DB data source

I recently installed SQL Server 2000 Reporting Services and connect to
a number of disparate data sources -- except a CA Datacom/DB
(mainframe) data source.
Any ideas on how to connect to the mainframe data so that it has the
look and feel of an ODBC database? And if so, what are the products
involved?
Thanks,

I'm using CA-Visual Express to hit Datacom through the Client ODBC Driver. It's a bit tricky with the authorities. You have to make sure they're set at the ODBC level if you want more than read-only access. We've not quite worked out the details on this yet. However, you can import any datacom table through the same ODBC driver using MS Access and perform all queries through there. (Not graceful, granted, but it does work!)
Good Luck,
