Hi Lutz,
Im wondering if the following is possible in newlisp...
I could not find a function that does this..
i.e.
I have a list -> (setq A '( (+ x 1) (- x 2) ))
Now I want to COPY/MIRROR that list to B..
But in this manner that everything that is changed inside List A also will be changed in list B.
This means that list B is a Symbolic-Link/Mirror to list A..
everything changes in A changes in B..
(not reverse nessesarly)
>(setq A '( (+ x 1) (- x 2) ))
( (+ x 1) (- x 2) )
>(mirror A B)
( (+ x 1) (- x 2) )
> B
( (+ x 1) (- x 2) )
>(pop A 0)
( (- x 2) )
> B
( (- x 2) )
Norman.
as contexts are passed by reference you could do the following:
((+ x 1) (- x 2))
> (set 'B A)
A
> A:var
((+ x 1) (- x 2))
> B:Var
nil
> (pop A:var)
(+ x 1)
> B:var
((- x 2))

aaaaaa look... I realy must get starting on contexts now..because its
something i never use inside newlisp... Great example...thanks!
