1216	 Symbolic Derivatives Without List Processing Subroutines or Recursion	 A routine has been developed which computes and prints out the symbolic derivative of an absolutely continuous elementary function of one or several variables. No use is made of list-processing languages. The chain rule is applied and the result is edited to produce results as elegant and efficient as those obtained by hand computation. A subset may be imbeded in a formula translator to introduce a differentiation operator into an algebraic programming language.
