How to get a random letter in VB6?

I cannot convert those I see in VB.Net I wanted to create something like a "Word Factory" So I need to produce a random letter. I managed to get a random number using this

Dim x, first, last
first = 65
last = 90
x = Int((last - Min + 1) * Rnd + Min)

How about random letters from the alphabet? in VB6. Thanks.
