Maximum length for the workspace?

[djf4]

Hey all, I'm working on a sidescroller, and am making a horizontal level.
Needless to say, the length of the level is pretty long. I've managed to make the world scroll accordingly, but I can only get so far, as the length of the workspace seems to cap off after a little bit.
Do I have to cut my level over seperate frames, or is there a way to extend the workspace? I'd prefer the latter.

Thanks!

1.enclose your level inside a movieclip
2.scale the movieclip to a smaller size
3.continue designing the level
4.scale back
