A value of the data type "array" is a group of values which can have the same or different data types.

Values of the "character" data type consist of one or more ASCII characters.

The data type "code block" designates a value containing executable code.

The "date" data type identifies values representing calendar dates.

There are only two values for the "logical" data type: true and false.

The data type "Memo" specifies a field variable which can store a character string of variable length.

For the data type NIL, there is only one value which can be defined in a program.

The data type "numeric" identifies values that can be used in executing mathematical operations.

The data type "object" designates a value which has its own variables and program code.
