[plt-scheme] defining macros in mzscheme 103

[Deva Seetharam <deva@media.mit.edu>]

hi all
i am trying to define a macro like this
(define-macro (new-core) `(make-vector 4 0))
	
when i run this in mzscheme within emacs, it gives me
the following error message:
"define-macro: not an identifier at: (new-core) in (define-macro 
(new-core) (quasiquote ...)"

what is wrong?

thanks,
Deva Seetharam
