PURPOSE:To perform program developings which are high in debug effect of the programs, by making an arrangement that, even when the external data memory is increased in number, the number of connectable controlling object will not be reduced, and, moreover, programs can be stored in the increased memories and performed. CONSTITUTION:An MPL support program is started by turning on a test switch 14 and depressing a general switch 13. Then, a write switch 11 is depressed after addresses to which the writing is made and data to be written are set, with the aid of the program, to an address switch 8 and data siwtch 9. By repeating this procedure, instructions to be jumped to the forefront of the program to be moved are written in the repeating area on an RAM5. When an RAM starting switch 12 is turned on under this condition, the program on an ROM4 is moved to the RAM5. When the switch 12 is turned on after the jumping location is changed to the forefront address of a program to be debugged, the program to be debugged can be executed. |
