Boolean.
The Boolean type is a predefined enumerated type that indicates logical
values. The elements of this data type are two constant identifiers,
true and false , where false is less than true . HP Pascal defines the
type Boolean in the following way:
TYPE
Boolean = (false, true);
Permissible Operators
