摘要

PROBLEM TO BE SOLVED: To make the operation contents of a multi-task object-oriented program easily understandable for a user and to efficiently debug a program. SOLUTION: The debugging supporting device is provided with a task information recording means 5 for recording the execution information of a task A, the task B and the task C executed in a multi-task processing by an OS (operating system) 1, an object execution information recording means 4 for recording the information of respective objects operated by the tasks, an information merging means 6 for time sequentially merging respectively recorded object execution information and the execution information of the task A, the task B and the task C and storing them in a history storage means 9 as the operation history of the program and an output data generation means 8 for generating output data for which the execution progress of the respective task A, task B and task C and the movement of the respective objects are linked based on the operation history table of the history storage means 9 and outputting them to an input/output means 7 (monitor).
