PURPOSE:To attain reprogramming on a track by writing data in a RAM corresponding to an instruction code using no operand code when an abnormality is generated in a mounted program. CONSTITUTION:At the time of deciding necessity during the processing of the mounted program 5, reprogramming data outputted from a ground station are written in a spare area 9 by a command program 8. In addition, a reprogramming processing starting address in a work area 6 is similarly written in an address table 7 by the command program 8. The address table 7 is entered to a RAM corresponding to a position on which control is to be transferred to the processing of the reprogramming in the program area or other processing in the program area 2, and an instruction code using no operand code and data commanding the transfer of control to the address are similarly written by the command program 8. Consequently, reprogramming on the track can be attained.
