[ColorForth] How to escape from loops

[Alex Thiel <alex.lists@xxxxxxxxxx>]

Hello,

I can't seem to figure out how to escape from a FOR loop properly if some 
exceptional condition occurs. I want to write something like this:

: loop for cond? if default next ; then exception ;

After "exception" has been executed, the loop should terminate. I guess I have 
to shuffle the return stack a bit for this to work, but I don't know how. 

Can anyone give me a hint?

Cheers,

	Alex
