If your forth allows it you can get around this by defining one of the
	words as a dummy ie. : firstword ;

The name is now in the dictionary so you can use it in the definition
	of another word ie. : secondword firstword ;

If you now edit the first word it can reference the second
	ie. : firstword secondword ;

A quick redefine will then sort out the dictionary and hey presto recursion.

As I said, your forth may prevent you doing this, mine allows it.
I'm not sure what the standard(s) say about it.
