Abstract : In the paper the underlying principles that are involved in the theoretical formulation and implementation of symbolic algebraic languages on the computer are defined and examined. After a brief discussion concerning the initial components of such languages, the major issues that are considered are the use of functional expressions and exponentials, control and modification of the mathematical machinery of the language by its user, and chains of multipurpose models. It is noted that general chains possessing two or more models provide the most desirable environment for allowing the analyst to simplify mathematical expressions containing various types of data (polynomials, trigonometric and elliptic functions, etc.). The language FLAP is used for illustrating many of the concepts involved, and their resulting consequences. (Author)
