I know what free variable are. I don't know the specifics of what 'free variable calculation' is. Testing whether a partiular variable is free? Determining the set of free variables? And what, roughly speaking are these linear and quadratic-time algorithms? -- hendrik ____________________ Racket Users list: http://lists.racket-lang.org/users
