Run parameter query using VBA

[Gerry Goldberg]

I am trying to learn to user Parameter queries. My simple test query is:
PARAMETER [Account] CHAR ;
SELECT * FROM tblAccount WHERE [Account] = "123456"

In my VBA code, I have determined that I want to run this query with [Account] = "654321"

How to I put this in code? Does the query have to be stored in QueryDefs?

Thanks,
