This volume describes the subprogram designated as Executive which has the abbreviation EX in the program listing Volume XII. Historically, the label Main Program has been given to that primary software routine that encompasses the main body of program calculation and requires a large amount of execution time. The interrupt routine is one that temporarily preempts execution of the Main Program in order to initiate a subroutine of time dependent nature. Here, however, the time dependent and sequential nature of the Submarine OMEGA software has boosted the interrupt routine to eminence and reduced Main Program to the state of marking time, or idling. Main Program will initiate the executive routine at start-up and then will continually check core until interrupted.
