In DB Pro, you don't #include. You add additional dba files using the editor.
That's a better explanation of what I'm trying to do. Add additional dba files using the editor. In fact, I've already done that, I am just wondering how to access them.

[Edit] That thread really helped! This picture explains it perfectly:

It turns out if I load for example: cool.dba then to execute it I would simply put cool(). Wow I feel dumb! Thanks
