Abstract

Through the use of a modified concept of cluster [1, 2] we propose the association of the notions of abstract data types and uniform reference to data structures to PL/I. The proposed programming mechanisms enhance PL/I by the addition of two new linguistic dimensions: a specification level and a common base language to handle the implementation of data structures. This report informally describes the syntax and semantics of the added constructs and gives an example of their use.
