<P>PROBLEM TO BE SOLVED: To provide a spreadsheet control program having excellent operability in creation and editing of a spreadsheet and data input/output in a computer with a touch screen such as a smartphone and a tablet computer while utilizing visibility of the touch screen. <P>SOLUTION: A spreadsheet control program recognizes a line drawn on a touch screen with an input window open as a border in parallel with a row or a column on a spreadsheet. When the borders define a quadrilateral, the program sets the quadrilateral as a cell on the spreadsheet. This allows a user of a computer to create a spreadsheet only by drawing lines on the touch screen with a fingertip or the like and to input a value in a cell by specifying a quadrilateral part drawn with lines and performing data input operation, thereby providing an interface for creating a spreadsheet, taking advantage of visibility and operability of a touch screen. <P>COPYRIGHT: (C)2012,JPO&INPIT |
