Hi Mark, > surely it would be just as easy to test whether local words or refinements are set, ie with the function Unset? as >opposed to none?.
Mine is only an idea, i'm not sure this is the true reason, but a none value can be used directly in expression like: if ref [...] either ref [][] An unset value would generate an error in these cases. Unset? can't be used with an unset word (the evaluation of the word gives an error), you must use: value? lit-word or unset? get/any lit-word As you can see it is not the first thing one could try :-) --- Ciao Romano -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
