Abstract

The purpose of the study described in this paper was to develop a computer program that enables users arbitrarily to define symbols and to instruct the computer to manipulate and to operate with them on-line according to the rules of their definition. An additional goal was the use of this symbol manipulation capability for constructing on-line programs that perform analytic operations upon algebraic expressions; the results of this work will be briefly mentioned in this paper.
