Assignment

Assignment is the act of changing the value of an existing variable. A variable's value may be changed to any value that is a subtype of the variable's declared type.

The act of assignment is accomplished with the use of an assignment phrase. The expression used in the assignment phrase must evaluate to a subtype of the variable's type.

Grammar: VARNAME := EXPRESSION

Example: humidityPercent := 50 + 20

NB: These code excerpts show assignment phrases. An assignment statement, like any statement, ends in a semicolon.
