[Scm-discuss] cannot use syntax-rules in scm 5e5

[Shuangyang Yang]

Hi all,

I downloaded SCM 5e5 from the website and try to learn macro. When I
tried the examples in the scm manual, I confronted an error saying
that "syntax-rules" is "unbounded variable", while "define-syntax" is
defined. I don't know what happens and cannot find any information
through Google. Is there any file I need to load first? Hope anyone
can help me. Thank you very much.

(On windows XP system)
