SALE, a simple algebraic language for engineers

that the connector A re-enters the program with the reading of the next symbol, the connector B enters a subprogram which determines whether recording or compiling is to follow, the connector D enters a recording subprogram, and the connector C enters a compiling subprogram. If eompilatiort has been started by the appearance of an operator (t = l), then compilation continues until a left-hand parenthesis is reached (39), or the proper X,~ value is encountered (43, 44). The operator which caused the compilation is then recorded by switching to connector D (54 or 55). The switch q is always set to 2 after compilation to prevent art improper assignment of temporary storage at the time of recording the next operator (33). The sub-program 49, 50, 5:l, 52 provides the proper assignment of temporary storage symbols. The contents of ,~ will always be some %, at the time box 48 is entered. The effect of the sub-program is equivalent to the act of inspecti~ag Tn for its n-value, and increasing n by unity.
