Abstract
A data type is a collection of values and a set of operations which may be applied to a variable of that type, yielding a result which may or may not be of the same type. Modula-2 has five built-in scalar data types- CARDINAL, INTEGER, REAL, BOOLEAN and CHAR. A scalar data type is one which represents a single value at any one time; the more complex structured data types which represent groups or sequences of values are discussed in Chapter 6.
