It depends what protocols/drivers your 'mainframe' supports/has. Most
modern ones AS400, etc support ODBC and this can be accessed via Data>Get
External Data>New database query... If your 'mainframe; is in the list of
drivers installed as you travel through the wizard, then you're set to go.
If no you will need to ask an admin if drivers are available and get them
installed locally on your machine (ODBC would be the easiest)
