PURPOSE:To purchase the software at a price equivalent to the capacity, the performance, etc., of said software by providing a using frequency recording part and a limited using frequency recording part for software on a floppy sheet and using a control means which discontinues the execution of the software after the software using frequency reaches a limited level. CONSTITUTION:A using frequency recording part and a limited using frequency recording part for software are provided on a floppy sheet. A control means is added to discontinue the execution of the software when the software using frequency reaches a limited level. Thus it is possible to give the limitation to the using frequency of the software which is solid on the market via the floppy sheet. As a result, the selling price of the software can be set at the value equivalent to the limited using frequency set previously. |
