A survey of currently implemented Pascal extensions
Thomas N. Turba, S. H. Costello · 1981
This document presents an overview of the more common and useful Pascal extensions that have been implemented to date. It describes, in general terms, the functionality introduced by these extensions and provides a rationale for the implementation of many of them. Examples are provided to give the reader a better idea of how each extension was implemented without going into great detail or formality in describing the syntax and semantics used by each implementation.
