Abstract

This paper describes a system of coding a general-purpose digital computer so that differential equations may be solved easily and rapidly. While originally developed for an IBM 701, the system is applicable to any of several large computers, in that at no stage is any reference to a particular machine needed. The process is such that any engineer who has learned how to set up an analog computer should be able to code without hesitation, and should have very little difficulty even if no prior computer experience exists. No attempt has been made to solve partial differential equations. The present system could be used, but would be inefficient in all but the simplest problems.
