CONSTITUTION:In case an error arises during an execution of program, a program piling is not given to the mode but the specified key(key or key ) is operated. Thus the program containing an error is displayed for the time during which the specified key is pushed. At the same time, a cursor display is given to the area where the error arised. The next or preceding line is displayed to the program that is displayed with every operation of the specified key. As a result, the factor of error is known without carrying out any mode switching. |
