I'm not sure that I understand what you mean by inparameters, but if you just read the script file into a string variable, then execute that string variable as a command, then you should be "good to go".
We are currently (trying) to create an application with Access forms and SQL server database with stored procedures. If you can get out of it, please do. Certainly the part with the stored procedures parameters is a hell. I would also suggest MSDE with osql.
But, probably, you can't drop the Access, so if you can supply some more info and i'll look into it.
