OK. After looking things up, I see Racket is a language related to Scheme. Its implementatin is an implemetatin of Scheme. That said, it has a *lot* of extra stuff that makes it a more generally useable language. What I answered above applies to the Scheme language in general, not specifically to the Racket implemetation. > > > > > -- In general computing, how does the random function work?
