2. Description of the Related Art Microsoft Visual of the United States
Visual such as Basic (hereinafter referred to as VB)
l When an application program using an input / output screen is developed using a development language, a window created at the time of program creation (design time) is called a “form” in VB. Form
This is a component for setting the attribute information of the OBJECT that performs screen input / output for the number of OBJECTs that perform input / output, and is defined using a component called “Control” in VB.

At this time, as a general method, according to the OBJECT defined at the time of design, the input / output position on the screen, the size of the OBJECT, the property (Property) of the OBJECT, etc. are statically defined using the control. are doing.

Similarly, for file input / output associated with screen input / output, a structure indicating input / output items on a file layout is defined by the number of layouts at the time of program creation, and this structure is used. File input / output is performed for each item.

[0005]

However, the conventional information processing apparatus using the above-mentioned Visual development language has the following problems.

That is, when creating an application program using a screen, the number and length of information to be input / output on one screen depend on the physical size of the screen (more precisely, the screen resolution). It is limited to a certain value.

For this reason, when there is a large amount of information to be input / output, it is necessary to create a screen input / output application after dividing a plurality of OBJECTs, which should originally be arranged on one screen, into a plurality of screens.

However, when one screen is divided into a plurality of screens as described above, each Form is defined for each screen to be divided, and each Form is defined and arranged on the screen.
Ontrol has to be defined, and there is a problem that the labor for development increases by that amount.

When one screen is divided into a plurality of screens, it is necessary to incorporate a function for performing screen transition. Therefore, as the number of screens increases and the number of screen divisions increases, the application program However, there has been a problem that the development labor of the system has increased dramatically.

Further, conventionally, since the OBJECT of the screen is statically defined, it is difficult to change the layout of the screen, and when a situation arises in which the layout needs to be changed, it is reviewed from the screen design level. There is a problem that the work and the change work have to be performed, and the trouble is increased.

Further, using one layout,

Therefore, when the file layout is changed / added, the structure must be changed and added, and the input / output processing must be changed / added to the changed screen item. , The time was hard.

Naturally, such a definition is statically defined (coded) when designing an application program. The I / O processing for the items and the like had to be coded independently, which was troublesome.

Further, regarding the file input / output items, since the screen input / output items are closely associated with the file input / output items, when the screen layout is changed, the file input / output items are changed in accordance with the changed contents. The output description (structure and file input / output instructions) and the like must also be changed, and there is a problem in that it is troublesome.
