Abstract
Pascal is widely used, primarily in university computer science departments. Pascal belongs to a new class of languages reflecting the importance of data management in the expressive power provided, enabling the programmer to deal more efficiently and precisely with the processing and management of data. Pascal incorporates most of the data facilities of Cobol and PL/I, but offers a new richness of expression set in an Algol-like framework. A primitive data type is a finite, ordered set of values. Not only do primitive types include the familiar Boolean, integer, and real, from Algol, and type char (for character), but other primitive types can be defined just by enumerating the values belonging to the type. A comment may appear anywhere in a Pascal program where a blank—not a part of a character string—may be placed. It is possible to explicitly declare a variable to be a pointer to a particular type of data.
