3.2 VARIABLES

Variables are symbols used to represent data items, such as numerical values or
character strings that are used in a BASIC program. The value of a variable may be
assigned explicitly and can be changed during the execution of a program. Be aware that
the value of a variable is assumed to be undefined until a value is assigned to it.

The variable name cannot be a BASIC reserved word.
