I define a function along with the usual parameter definitions and then go on

the append command to append a sequence of geometric objects, but find that
the function I had defined earlier in the code isn't recognised.
If you do
(define (foo arg1 arg2) ...)
then "foo" is defined at all later points in the file. Probably, you are
misdiagnosing the error.
The second problem I had was that, using a "do" loop within this
"append" scope doesn't work {compile error}, but the same "do" loop
works out side the "set! geometry" scope.
"do" loops work anywhere. Probably you are just misunderstanding the
syntax. Personally, I find "map" easier to use than the Scheme "do"
syntax. See also the section on "loops in scheme" in:
