Scheme Formatting Help - scheme

Question

I've been working on a project for school that takes functions from a class file and turns them into object/classes. The assignment is all about object oriented programming in scheme.
My problem however is that my code doesn't format right.
The output it gives me whenever I give it a file to pass in wraps the methods of the class in a list, making it so that the class never really gets declared. I can't for the life of me figure out how to get the parenthesis wrapping the method list to remove.
I would really appreciate any help.
Below is the output, the class file and the code,.
(define pointInstance
(let ((myx 1) (myy 2))
(lambda msg
(cond
(((eq? (car msg) getx) myx)
((eq? (car msg) gety) myy)
((eq? (car msg) setx) (set! myx x))
((eq? (car msg) show) (begin (display "[") (display myx) (display ",") (display myy) (display "]"))))))))
If you look at just after the cond you'll see how all those eq statements are contained in a list. I can't get this to work right unless they're not wrapped by that top level list.

(class pointInstance (parent:) (constructor_args:)
(ivars: (myx 1) (myy 2))
(methods:
(getx () myx)
(gety () myy)
(setx (x) (set! myx x))
(show () (begin (display "[") (display myx) (display ",") (display myy) (display "]")))
))
(require (lib "trace.ss"))

(cons rec (load-file port))))))
;; Open a port based on a file name using open-input-file
(define (load fname)

[(null? listToMake)
retList
;(display "The list passed in to parse was null")
]
[else

]
)
))

Answer 1

You have too many opening parenthesis in the 1st clause of the cond.
IE:
(((eq? (car msg) getx) myx)
^
Updated:
Are you looking for this?
(cond ,#(makeMethodList classMethodList '())
^^
Or you can do:
(cond . ,(makeMethodList classMethodList '())
