True, but that does make it a little more awkward for making a generic 
function.

A highly contrived example follows

public function inc(input as integer) as integer
    ' increase input by 1 and return input * 2

   input = input + 1

    return input * 2

end

public sub main()

    dim i as integer
    dim j as integer

    i = 1
    j = 2

    print inc(i) ' i == 2 displays 4
    print inc(j) ' j == 3 displays 6

end

Of course the above wouldn't work if input were passed ByVal and would 
require two functions or as you say declaring i and j as public but that 
isn't good practice, not at all ;)
