autolisp for checking what the current / active space is..

Hi,

I'm not too hot on autolisp and need to know how to check what the current / active space is..

ie: if active space is modelspace then blah blah
else if active space is paperspace then blah blah blah

basically, i want to swap to a different dim style dependent on which space i'm in.

any help would be great, thanks
