MSWord 2003 Spelling/grammer ignore block of text or a particular style

I'm using MSWord 2003.

I'm writing a report that includes blocks of code etc. I want any spelling or grammer mistakes to be ignored for these blocks.

I've defined a style for a block of code, but i can't find any way of getting it to ignore a particular style (or even a range i select) when checking S&G.


Any ideas?

Cheers.
