You need to declare the return type and types of each parameter. Forget the SET PROC, you don't use that.

An example would be:

DECLARE INTEGER _fpreset IN msvcrt20 STRING, STRING, INTEGER

I normally put the parameter name after each declaration. If you pass by reference, use the @ before the name.

If you require boolean (logical), use INTEGER.
