<p>PURPOSE:To make unnecessary the programming of a calling procedure and to facilitate the help function development by giving at any time the request of the non-synchronization called as a message to software as an input for a help function part and each function part except it by a main body part. CONSTITUTION:A main body part registers (300) the class of each function to a system so that respective procedures can be started by a message, registers (310) the class of the help function to the system and processes actually each type of the message by a message processing loop (320). A help function part receives and starts (330) the message of the help starting and displays the help screen (340). Further, in the message processing loop, until the message of the function selection by the key operation of a user is received, each type of the message is processed (350). When the function selection message is received, next, it is issued as it is, by using the mechanism of the message issuing emulation held by the system (360).</p> |
