SetValue Command

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).

Example: If f is a function, SetValue[f, RandomElement[{cos(x), 3x+2, ln(x)}]] defines, at random, f as being one of the functions proposed in the list.

SetValue[ <Boolean b>, <0|1> ]

Sets the state of a boolean / check box : 1 = true, 0 = false

Example: If b is a boolean, SetValue[b,1] sets the boolean b as true.

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.
