Hi,

I tried building a standalone logo interpreter with your code, but had to make some small changes to make it compile. I am using Gambit-C release 4.9.3.
Changes are in Logo.patch.txt , a short summary of changes is below:

• moved scheme macros to a separate file, macros.scm
• changed definition of define-class macro to: (define-macro (define-class form . rest) `(make-definitions (quote ,(cons form rest))))
• created new file mylogo.scm
• change exit-logo procedure to call (exit 0)
• additionally check for EOF object in line-obj in logo.scm
• maybe-num is redefined in logo.scm, line 419. Rename that instance to logo-maybe-num. It isn't called anyway.
• To compile program; gsc -exe mylogo.scm

Let me know what you think.
