Include code from an external .as file - error?

When I try to include code from the external file “test.as” I get an error:

“ActionScript 2.0 class scripts may only define class or interface constructs.”

“test.as” contains a simple function:


function test () {
trace(“test”);
}

I put:

#include “test.as”

in my .fla.

I thought I could edit code in an external editor. Could somebody enlighten me if that’s possible?
