Data abstraction for Pascal programmers

Published: 07 June 1982 Publication History

Abstract

Lack of data abstraction facilities in Pascal is a serious shortcoming for a language whose principal aims include "teaching programming as a systematic discipline." In this paper, a scheme is presented to implement data abstraction in Pascal using a limited form of the class structure defined in Concurrent Pascal. The class structures are translated to equivalent (sequential) Pascal constructs with the help of a preprocessor whose design is also described.
