[REBOL] RAMBO #3652 unset?
From: apwing:zonnet:nl at: 22-Mar-2005 12:06
thanks for your explanation in RAMBO.
Still I have a few remarks / questions.
#1. it seems very odd to me that unset and unset? are in fact unrelated!
Unset causes a variable to have it's value removed.
Unset? checks for datatype unset!
#2. Is () the only "thing" with datatype unset! ?
If not, what other "things" have this value ?
Could you give one or more practical examples of the use of
unset! and unset? ?
