Abstract

Each program element of a desired program is converted into a corresponding graphic element and is displayed on a screen of a display, which enables a schema of the program to be visually displayed as graphics on the screen of the display. When the program is executed, the graphic elements corresponding to the program elements of the program under execution and a graphic element corresponding to a program element under execution are displayed on the screen of the display in a visually discriminated fashion. When necessary, the execution count of each program element is displayed in the neighborhood of the program element on the screen of the display. Or, according to the execution count of each program element, the color of the displayed graphic element of the program element is changed on the screen of the display.
