I've found Hit's driver to be faster and lighter[1] than IBM's OLE/DB driver. But's it's personal preference. -Walden [1] I HATE installing ~30 Meg of crap just for a database access driver like I have to in CAE. ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 WaldenL@TechSoftInc.com http://www.TechSoftInc.com -----Original Message----- From: thomas@inorbit.com [mailto:thomas@inorbit.com] Sent: Wednesday, November 21, 2001 9:14 PM To: midrange-l@midrange.com Subject: RE: Changing column names? Walden: Then what is the Hit Software middleware itself used for? Why have it? Why not direct connects? (Yes, the library list of the connecting user can be used both for ODBC and DRDA/DDM.)
