Abstract: PURPOSE: An interpretation and real time execution method of a function block type process control program is provided to define a unit element of a control operation as a primitive function for a program formation and execution for a process control and easily use a function block formed by grouping a high frequency portion as one element like a service routine of a computer language for thereby implementing an efficient control program. CONSTITUTION: A function block is interpreted. A function block source function group arrangement which includes a unit arrangement with respect to each source function of the function block is generated. A function block source function code arrangement which includes a pointer which indicates a function block source function group arrangement with respect to a source function included in the function block is generated. A function block region variable arrangement is generated for storing variables used in the function block. Source function group arrangements which include a unit arrangement with respect to the source function are generated. A source function code arrangement which includes a pointer is generated. System region, input and output and region variable arrangements are generated for storing the variables. A function block source function code arrangement is copied to the source function code arrangement.
