Abstract: An automatic software component creating system includes a software component definition data storage section which stores software component definition data therein, a software component creation rule storage section which stores software component creation rules therein, and a client program creation rule storage section which stores client program creation rules therein. A software component creating section creates a software component module with one or more software components based on the software component definition data and the software component creation rules in response to a start instruction. A client program creating section creates a client program source code based on the software component definition data, the software component module, and the client program creation rules, when the software component module is created.

Abstract: In an X window system in which a work station 10 and a plurality of X terminals are connected, screen information managing means 50, upon actuation of a program 70 from an X terminal, if the preset number of X terminals on which screens of the program 70 can be displayed is greater than the number of X terminals in a screen information managing file 60, or information concerning the X terminal which has requested actuation of the program 70 is already present in the screen information managing file 60, or there is any X terminal whose process number is 0 is present in the screen information managing file 60, updates the screen information managing file 60, and at the same time notifies operation possible/impossible judging means 30 that screens of the program 70 can be displayed on that X terminal; and the operation possible/impossible judging means 30 controls the execution and interruption of the program 70.
