PURPOSE:To easily perform receipt and delivery of variables, by describing differences between cases where only values are received and delivered between the main program and subprogram and where variables themselves also are received and delivered. CONSTITUTION:When two programs having independently different variables are executed through reception and delivery of data in an electronic computer composed basically of a CPU2, an ROM3, and an RAM4, descriptions as shown in (a) are made when the value of the main program is delivered to the subprogram. In the (a), A( and X( ) represent whole array and names of variables put in parentheses represent that only values are delivered. Moreover, when not only values but also variables themselves are to be delivered, descriptions as shown in (b) are performed, and A( ) and X( , and B and Y show that data themselves are the same. When values of X( ) and Y change in the subprogram, values of A( ) and B in the main program also change. |
