PROBLEM TO BE SOLVED: To flexibly and easily handle an unexpected situation and accurately reflect the handling content to routine operations even when such a situation occurs while a computer executes routine operations.;SOLUTION: If a start confirmation check is set to request an operator's intervening operation before task execution during the execution of routine operations, the routine operation execution is suspended (S3) to determine whether or not to execute an undefined task according to the operator's direction (S4). If an undefined task is to be executed, the undefined task is defined (S5) and then executed (S6), and execution information including the execution result is recorded in a database (S7). If an end confirmation check is set to request the operator's intervening operation after task execution during the routine operation execution, the routine operation execution is suspended and, in the same manner, an undefined task is executed and execution information is recorded in the database.;COPYRIGHT: (C)2005,JPO&NCIPI
