Hi Ladislav
Your are right as I expected.
error? try [get/any :word] :== true
error? try [error? get/any :word];== false
Facts are facts ! I'll have to spend some time to digest this.
"Lentement mais surement". BTW your french is pretty good. With minor
correction it goes like this "Personne n'est tomb� du ciel savant." (where
"savant" qualifies "personne" not "ciel").
I think the same idea is expressed by "Personne ne sort savant du ventre de
sa m�re."
Encore merci pour cette lumineuse r�ponse.
Patrick
