A block diagram compiler

A computer program known as BLODI, which accepts for an input a source program written in the BLODI language, is described. The BLODI source language corresponds closely to an engineer's block diagram of a circuit and is easily learned, even by persons not familiar with computing machines. The input code consists essentially of designating the connectivity of a number of boxes drawn from an alphabet of about 30 types. These types include amplifiers, delay lines, counters, etc., which are familiar to designers of electronic circuits. The principles of the compiler are explained and applications are discussed.
