PROBLEM TO BE SOLVED: To easily achieve a mechanism for canceling commands that have already been sent from a server to a client. SOLUTION: A server creates an anti-command for canceling a command and inserts it into an execution queue. A client disposes of both the command and the anti-command when the command and the anti-command corresponding to the command are stored in the execution queue at the same time. Alternatively, the server may generate an anti-command for canceling a command and insert it into the execution queue in advance. COPYRIGHT: (C)2005,JPO&NCIPI
