<P>PROBLEM TO BE SOLVED: To provide an information processing program and an information processor for undoing operation processing without limitation. <P>SOLUTION: When updating information, existing perpetuation information 26 is kept as it is, and an updating management part 14 generates updated information 24. An operation history management part 12 generates operation history information 23 and stores it in a storage part 21. In each operation, an operating position management part 11 updates current operating position information 22. When an operation is redone from an arbitrary operating position, the current operating position information 22 may be changed by an operating position processing part 18. Operation object information is not updated from other operators due to exclusive information 25, and the existing perpetuation information 26 before operation processing is presented to the other operators. <P>COPYRIGHT: (C)2009,JPO&INPIT |
