Abstract
When keys are typed on a calculator keyboard displayed on an scientific electronic calculator emulation screen, not only are key data items of the calculator stored sequentially into a key log memory and displayed on a log screen, but also a calculation process corresponding to the key input is executed and displayed on a calculator display. Then, when the “selector” button on the tool bar is input, a calculator function name to be executed on the basis of the key log displayed on the log screen is retrieved from a function corresponding key log memory and is replaced with a display area of the key log. Then, the display area is displayed. Accordingly, with the key logs displayed on the log screen, what processes the series of key logs are supposed to execute can be recognized easily.
