Zusammenfassung:	The author attempts in this survey to define the notion of 'abstract data type' and discusses several important issues related to their use in high level languages, including encapsulation, exportation, parameterization, pointers, extent, coercion, assignment, initialization, and literals. The programming languages Algol 68, Simula 67, and PASCAL are chosen as a representative set of type-extendable languages and are compared and contrasted as to their treatment of these issues. Proposals for new languages or facilities made by Liskov, Wulf, and Morris are included in the discussion. Sponsored in part by DARPA.
