To obtain information managed by a program without starting any other application program.

A user inputs a reading character string and presses a conversion key, and then candidates are displayed (ST7). With an instruction generation key pressed, it is judged (ST13) whether or not there is a character string matching instruction generation reference data among the conversion candidates. When there is the character string matching the instruction generation reference data, an instruction for performing a certain process for the character string of a variable part is generated and outputted (ST15). According to the outputted instruction, a process instruction is supplied to a module program of the corresponding application program. After the process by the application program is completed, the obtained result is displayed.
