PROBLEM TO BE SOLVED: To enable a user to know the trial state of trial software and also to systematically use this software. SOLUTION: A system date acquisition means 1 acquires the system date, a trial limit date acquisition means 2 acquires the trial limit date of the trial software and a trial limit date comparison means 5 decides that the system date exceeds the trial limit date. Under such conditions, an executing LM comparison means 10 decides that an LM constructing the trial software is included in the LM that is presently carried out by a computer. Thus an LM interruption means 11 compulsively interrupts the former LM. When the system date does not exceed the trail limit date, a message output date comparison means 12 decides that the system date exceeds the date when the trial limit date is notified to a user. In such a case, a message output means 13 outputs a message to show the decision result of the means 12. |
