Abstract: Upon receiving entry of a dial key on a standby screen (80a) of a mobile phone, a sequence of numerals corresponding to the entry is displayed on a screen (80b), and the mobile phone becomes ready for making a call to a phone number represented by the displayed sequence of numerals. When any dial key is entered six times in succession, a function name “IrDA” is searched for, which relates to letters “ir” identified based on entry of the dial keys of “4GHI”, “4GHI”, “4GHI”, “7PQRS”, “7PQRS”, and “7PQRS”, and then the function name “IrDA” is displayed as an alternative (84) on a screen (80d). At the same time, a sequence of numerals “444777” is displayed as an alternative (85). Upon receiving selection of the alternative (84), an infrared receiving function is executed as shown on a screen (80e). Upon receiving selection of the alternative (85), it becomes ready for making a call to a phone number represented by the sequence of numerals “444777” as shown on a screen (80f).
