Sorry,
I ment of course list....

what I exaclty ment is

that if I assign

value = Number

that I automaticly assign y[1][3][6][1][1] a new number.

more detailled explained:

let us say a would be x = [2,5,4]

y = a[3]

if I change y to []

I want the result to be x = [2,5,[]] and that's automaticly
independently how deep i dig.



Sorry for the inconvenience.


Tamer
