To automatically start an appropriate complication program only by instructing data which a user is to compile even if plural types of data are operated.

When character data is inputted, a character data flag is turned on (step S205). When graphic data is inputted, a graphic data flag is turned on (step S206). When picture data is inputted, a picture data flag is turned on (step S207). These data are stored by adding the flags to various data. When arbitrary data in various data is instructed (step S208), an appropriate compilation program for compiling data is judged and started (steps S209-S213) by the type of the flag which is turned on with the flag added to instructed data.
