I know weak typing has been a useful feature in FoxPro, but sometimes I want to enforce strong typing. But according to the following code, that's not possible!

?squareit("5")


FUNCTION squareit
	LPARAMETERS x as Double
	
	?"have we encountered a problem yet?"

	RETURN x * x
ENDFUNC 

My initial thought was I should get an error on the call to squareit(), since I am passing a character type when it expects a double. But the error doesn't happen until I perform the calculation. This isn't right! If the caller screws up the function call, I want the error to originate there, not buried in the well-debugged function!

I haven't noticed this before because I assummmed FoxPro was enforcing my explicit type. Am I doing something wrong, or is this just one of FoxPro's quirks?

Using VFP 9, no service pack...
