Title: Assignment to Subscripted Variables
Authors: Gries, David
Keywords: computer science
technical report
Issue Date: Mar-1977
Publisher: Cornell University
Abstract: The assignment b(r):=e is investigated using two axiomatic definitions in order to gain an understanding of the problems involved with using arrays. It is seen that assignment to array elements leads to many of the difficulties encountered with pointers or references. The axiomatic definition is extended to cover the multiple assignment statement to both simple and subscripted variables, and a proof of correctness for a nontrivial program is outlined using the new definition.
