An information processing apparatus obtains a distance that an input pen is moved in terms of the number of dots covered on a display screen, and from that number, judges whether a pen stroke is a gesture entry or a pointing entry. When the input pen is moved over more than a predetermined number of dots, e.g., eight dots, gesture recognition processing is performed. If the input pen is moved less than that number of dots, a pointing instruction is recognized, and pointing processing is performed. If a gesture is recognized, a recognized gesture editing command and a feature point of the gesture command are stored in RAM. Since an input by the input pen is judged a gesture entry or a pointing entry according to the number of dots over which the input pen is moved, a switch is not required to change data/instruction entry modes which reduces cost and improves handling.

A display for use in a computer, for example a word processor or a personal computer, includes a device for forming a help message on the display. The help message can provide help when an error occurs in operation. Also a help message can be provided for a current mode when a help key in depressed thus assisting the operators even though there is no error.

A word processor may be used in a plurality of languages such as Japanese and English. The word processor has a function of replacing a particular symbol added with an editing symbol with a described character in automatic editing text. The capability of adding of the preferred edit data (edit symbol) to a series of particular symbols is done by arranging newly inputted data in positions of the particular symbols so that the desired edit can be performed. Where a number of newly inputted characters is smaller than that of the particular symbols, they are replaced with space codes or they are deleted. This prevents unnecessary symbols or spaces from remaining in a simplified format.
