That's the questio, how does one pass a paramter by reference, on a function declaration?

You can fudge it by passing in an array and modifying the contents.

Function Main:Int()
	Local arr:Int[1]
	Test(arr)
	Print arr[0]
	Return 0
End

Function Test:Void(someParam:Int[])
	someParam[0] = 5
End

well, my scenario is, I'm writing a default general purpose function that gets a string representation of an HEX number, and returns the interget value of the number AND a bool that determines wether it the conversion was properly done or not. So I can't really use an array as they're different types and using an object just to be able to make a funciton call seems a bit overkill, dunno... Isn't there any var or byref or * or anything to pass a variable by reference?

No.

Use an object, or use Poke() and Peek() in the new Data Buffer module. An object would be faster.

~~Or use an IntBox, as explained in the docs.~~ edit: huh, intboxes don't allow to be mutable...
