A string extension for Pascal
F. D. Boswell, M. J. Carmody, T. R. Grove · ACM SIGPLAN Notices · 1983
The Pascal language, as described by the ISO Draft Proposal or Jensen and Wirth, is deficient in its facilities for character-string manipulation. A proposal for an extension to Pascal which facilitates the manipulation of character strings is given. The extension consists of a modification to the "type compatibility" rules of the language, plus a set of pre-defined functions and procedures. The extension has been implemented in the Waterloo Pascal compiler and the Waterloo microPascal interpreter.
