Sorry, now I understood nothing. Why loop 2 [append [] 3] is equivalent to append append [] 3 3 that is some sort of "nested" expressions - result of first 'append is INSERTED as parameter for second 'append, while loop 2 [ append copy [] 3 ] is equivalent to append [ ] 3 append [ ] 3 that is some sort of "sequence" expressions - first 'append is FOLLOWED by second 'append? Why does not parameter substitution done? Valeri -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
