A couple days back I posted a problem in the "Other Languages" forum at:
http://www.dreaminco...wtopic65339.htm

Unfortunately I haven't gotten any response. It my be in the wrong place as it its subject lies between algorithms (Computer Science) and Scheme (Other Languages).

I'm still struggling here on day three, so this is just a crier's call for assistance. I would of moved it if I could. I didn't want to copy the whole thing here and get a stinging rebuke from the moderators.

Please, if you are fluent in Scheme and intuitively understanding of recursion, take a look at my above link.

Scouts honor - I'm not trying to get someone to explain recursion. For example:

(define factorial
	(lambda (n)
	(cond
	((or (< n 0) (null? n)) (quote ()))
	  (else
	  ((cond (= n 0) 1)
		  (else * n (factorial (- n 1))))))

>factorial 3

will execute a recursive send/return something like:



I do intuitively understand simple recursion. What I don't get is recursion within a recursion, as in my OP:

(define rember
   (lambda(a lat)
	   (cond
		  ((null? lat) (quote ()))
		  ((eq? (car lat) a) (cdr lat))
		  (else (cons (car lat)
					 (rember a (cdr lat)))))))

where argument:
a is and
and
lat is (bacon lettuce and tomato)

Please refer to my OP at:

for full explanation of my dilemma.
