A Decision Matrix as the Basis for a Simple Data Input Routine Currently a great deal of time and effort is being spent on the development of bigger and better compiler languages, multiprogram executive systems, etc. Since the implementation of of new methods and procedures is not instantaneous, but rather occurs by an evolutionary process, we should be concerned also with the problem of maintaining, improving and incorporating new ideas into existing systems. It is with this somewhat neglected area that the author is interested. A method employing a decision matrix is presented for the handling of a standard systems programming problem,that of providing a data input routine. CACM December, 1962 Vasilakos, G. J.
