Hello, Alain. You might wish to write out htdp.org design recipes for
EnumVarDim and Enum. I don't know what they're supposed to do, but is
the below code closer to what you want?
#lang racket/base
(define (Enum x)
(fprintf (current-error-port) "TODO: implement Enum\n")
x)
(define (EnumVarDim dim value)
(if (>= dim 2)
(Enum value)
value))
(define pairValue (EnumVarDim 111 222))
(printf "pairValue = ~S\n" pairValue)
In this code, the value of pairValue isn't being set inside EnumVarDim.
Instead, the value of pairValue is set outside of EnumVarDim, to the
value of applying EnumVarDim.
(BTW, if you wish to try Racket naming conventions, you could use names
like enum-var-dim and pair-value.)
