PURPOSE:To enable an operator to understand easily the loading state of a system program by displaying the loading progress state from start to end when the system program is loaded. CONSTITUTION:An initial program 13 includes 13 data in all, that is, graphic data 2-13 and a graphic data 1 of an initial state. Then the program 13 sets the data 1 to a graphic display memory 14 and displays 4-1 to a display device 4 through a graphic controller 5. This display shows the start of a program loading action. Then the program 13 progresses to load the first program to a memory 12 from a disk of a floppy disk device 9. Then the graphic data 2 is set to the memory 14, and the device 4 displays 4-2. Hereafter the display of the device 4 is varied every step with progress of the program 13. Thus it is possible to understand the loading state of a system program. |
