About Language Variables

A variable is a storage location and has an associated type, sometimes called its parse-time type, which is either a primitive type or a reference type. A variable always contains a value that is assignment compatible with its type. A variable's value is changed by an assignment or by a prefix or postfix 

++ (increment) or --
(decrement) operator.

Compatibility of the value of a variable with its type is guaranteed by the Expression Language. Default values are compatible and all assignments to a variable are checked for assignment compatibility usually at parse time, but, in a single case involving arrays, a run-time check is made.
