When you open a spreadsheet, the input line will become the spreadsheet, like the one shown in Figure 2.4. The top will be a menu bar with Table, Edit and Maths menus as well as eval, val, init, 2D and 3D buttons. To the right will be the name of the file the spreadsheet will be saved into. Below the menu bar will be two boxes; a box which displays the active cell (and can be used to choose a cell) and a command line to enter information into the cell. Below that will be a status line, which can be clicked to return to the configuration screen.
