[thelist] byref vs. byval clarification (was [Off-topic] --taboo!)

Can you tell sgd uses frontpage? He didn't close his tip tag...

Ok, here's a question:

function Yo(aNumber)
    anotherNumber = aNumber
    anotherNumber = 14
    Yo = true
end function

x = 1
good = Yo(x)

when this occurs in the function:

    anotherNumber = aNumber

is the reference assigned, or the value? In other words, does x=1 or does
x=14?
