The illustratino is cool, but it doesn't take into account the possibility of: @a[0] := $x; which means that an array is, theoretically, an array of item containers. Consider the following: @a[1] = 0; @a[1] := 1; @a[1] = 2; The first line store 0 in the item container initially created at position 1 of array @a, the second line replaces that container by the value itself, and the third line fails because "1" is a readonly value, not a container, so you can't store into it. Of course this is the theoretical model, and implementations should optimize whenever they can... daniel
