EvaluationStatement ::= Expression S? ‘;’

An evaluation statement appears outside the context of any other statement; it consists of just an expression and a semicolon.  Such statements are used for assigning variables and calling functions.

NullStatement ::= ‘;’

It is possible to just have a semicolon without an expression; this indicates a “null statement” that performs no action.
