ABSTRACT:
A program debugging system for a computer having an arithmetic/logic controller for implementing operations for data in accordance with a stored program and a program debugging device for issuing commands for correcting program errors to the arithmetic/logic controller, the system comprising a readout data addressing unit incorporated in the program debugging device for specifying the address of data which has caused an error in the arthmetic/logic controller, an address setting memory for writing the address specified by the readout data addressing unit into the arithmetic/logic controller, a data readout commander incorporated in the program debugging device for commanding the readout of the error-causing data in response to the input command issued on an input console provided in the program debugging device, a data hold/transfer unit for reading out data in the address set in compliance with the detection by an error detector in the arithmetic/logic controller and delivering it to a data receive/edit unit in the program debugging device, the data receive/edit unit receiving data from the data hold/transfer unit, editing the received data, and displaying the edited data on a display unit via a display controller.
