To add to what Paul said...

VB has the ability to use named parameters. Thats what the := is all about. So you can either pass parameters as you do in VFP (param1, param2), or with names (param2 := value, param1 := value). With names allows you to pass in any order.

>>Any functions in excel I've ever come across that use the := syntax, require you to pass these values as parameters to a function. Thusly, yours would look like:
