The specification of an action is called a statement. Statements can be interpreted (executed), and that interpretation (execution) has an effect. The effect is a transformation of the state of the computation, the state being represented by the collective values of the program’s variables. The most elementary action is the assignment of a value to a variable. The assignment statement has the form $$ \$ {\text{ assignment = designator}}{\text{: = }}{\text{ expression}}{\text{.}} $$
