- SetValue[ <Boolean>, <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[ <Object>, <Object> ]
- LetA be the first and B the second object. 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[ <List>, <Number>, <Object> ]
- Let n be the <Number>. The command SetValue sets the n-th element of a free list to the current value of the object. 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.
