PURPOSE:To eliminate fear that a user other than a spread sheet constructor breaks the contents of stored knowledge, and to use a spread sheet with confidence by providing a comparing means and an execution control means, etc. CONSTITUTION:The name of the constructor of the spread sheet is stored previously in a knowledge base 3, and at the time of the start of the use of the spread sheet, at first, the execution control means 2 requests an input means 1 to input the name of the user, and writes the inputted name of the user to the comparing means 7. Next, when an input is related to the input of knowledge, the means 2 instructs an execution suppressing means 9 to confirm the propriety of execution, and the means 9 reads the result of the comparison of the name of the user written in the means 7 and the name of the constructor in the knowledge base 3 through a temporary storing means 8. As the result, in the case of coincidence, the means 9 instructs the means 2 to continue the execution, and in the case of discordance, it instructs the stoppage of the execution. Thus, the fear that the user other than the sheet constructor breaks the contents of the stored knowledge is eliminated, and the spread sheet can be used with confidence. |
