SetValue[ <Object A>, <Object B> ]
If A is a free object or a Point restricted to Path or Region, its value is set to current value of B (i.e. A doesn't change value if B is changed afterwards).
SetValue[ <Boolean b>, <0|1> ]
Same as above; instead of SetValue[b,true] you can use SetValue[b,1], 0 can replace false.
SetValue[ <List L>, <Number n>, <Object B> ]
Sets n-th element of the free list L to the current value of B. Number n can be at most 1 + length of L.

SetValue in scripting[edit]

If you want to change value of an object in Scripting, always use SetValue rather than =. See Responsive Applets for more information.
