2. Description of the Related Art In general, a display device (CRT (Cathode Ray Tub)) is provided by software (hereinafter referred to as "screen use software") for performing data processing such as data registration, inquiry and correction through a screen in an interactive manner.
e) With regard to the screen displayed on the display device, etc., there is a possibility that the screen layout and input / output items may need to be changed after the user interface is visually confirmed during or after the development of the software using the screen. Is high.
Therefore, there is a demand to have the user actually see the screen in the early stage of development and to prevent a change in the screen layout and input / output items from occurring after the development.

In order to respond to such a demand, a demonstration (trial) using a demonstration screen is required in the development stage of screen use software.

Conventionally, in a demonstration screen creation / display system for creating and displaying a demonstration screen of this type, a demonstration screen is created and displayed in the following procedure. Such a procedure is the same as the procedure in the case where the screen is displayed by the normal processing of the screen using software. Screen display program (screen display program)
Creation of source program (eg coding of screen definition)
Is performed. Compiling and linking of the screen display program are performed. An operation environment for executing the screen display program after compiling and linking is set. After that, the screen display program is executed to display a desired demonstration screen.

[0005]

In the above-described conventional method of creating and displaying a demonstration screen, coding and definition of a screen definition (which is generally a difficult task) is required for creating and displaying a demonstration screen. Since recompiling and relinking must be performed even for slight modification of the demonstration screen, there has been a problem that the time and man-hours required to create and display the demonstration screen are increased.

Further, for the demonstration using the demonstration screen, it is necessary to set the same operating environment as the actual operating environment (operating environment when the screen using software is actually operated to display the screen). There has been a problem that a place where a demonstration using the demonstration screen can be performed is limited.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a demonstration screen without the need for coding a screen definition, compiling and linking a screen display program, and setting an operating environment for executing the screen display program. By enabling the creation and display, and by accumulating information on the created demonstration screen in a screen file, the time and man-hours required to create and display the demonstration screen can be reduced. An object of the present invention is to provide a demonstration screen creation / display method that can reduce restrictions on places where demonstrations can be performed.
