As you've learned, the parens are usually optional. But, if you need to get a return value from the method you are calling, they are required:

lnValue = THISFORM.MyMethod

Gives you a "property not found" error

lnValue = THISFORM.MyMethod()

Works.

What's more, including the parens in every function call is just good coding practice. Later on, after having written a ton of VFP code and having to maintain it, you'll appreciate the visual clue as to what the code is doing.
