Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a screen management method for creating, changing, operating, and maintaining a screen such as a man-machine interface used in a computer system. [Technology] Conventionally, in creating, changing, operating, and maintaining screens, the modularization and functions (subroutines, functions, etc.) and data structure definition functions (table definition functions, etc.) provided by programming languages have been used. Configure the screen management system. Therefore, the screen management method adopted depends on each system on a case-by-case basis.

[Problem that the invention seeks to solve]

The conventional method described above takes into consideration the fact that programs are frequently added, changed, and deleted on a single screen basis.
Nothing in particular was done. For this reason, when the screen specifications are changed, the parts of modules, data, etc. that are changed in response to changes in the single screen specifications tend to become unclear, and the number of errors that spread due to program changes tends to increase.
There were other problems.

An object of the present invention is to provide a screen management method that makes it easy to add, change, and delete programs on an m-th screen.

c) Means for Solving Problems] The above purpose is to combine screen-related data such as screen control-related data and screen display-related data, and modules (subroutines, functions, etc.) that employ them into one. This is achieved by providing a means for handling the data as a group of data.

[Effect]

With man-machine software that handles screens, it is possible to manage data, modules, etc., centering on screens whose specifications are subject to frequent changes. , programs (including data) can be added, changed, and deleted extremely easily.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

Figure 1 is a system configuration diagram of a frame system (tentative name) that supports the development of man-machine software by applying the hydraulic system. Here, a frame is a data 11g structure that is a collection of data and modules related to one screen, and its details will be explained with reference to FIG.

This system accepts screen components such as characters and figures, transition information between screens, etc. manually from a terminal 2, and uses a frame manager 11 to register the data in the system as frame format data, and converts the registered data into frame data. Frame memory 14. A frame interpreter 12 executes frame by frame in response to key information and commands input from the terminal 3, displays the corresponding screen and starts procedures, and a frame manager and frame interpreter 12 function as routines for accessing frame format data. It consists of frame interface routines 13, which are used by the interpreter and are also open to procedure modules.

2nd B! 1 is an outline of the man-machine software construction procedure using the frame system.

In Box 10, functions necessary for the man-machine are extracted, and these are centered on the man-machine screen components. Organize the relationship between data and procedures.

Here, data refers to one screen transition information, data information necessary to configure a screen, etc., and procedure refers to a procedure program etc. that performs necessary processing in relation to the component screen.

In box 20, the data and procedures associated with the screen components are integrated into a frame and registered in the system by the frame manager. Also.

Change or delete frame data as necessary.

Box: 30 uses the screen management function of the frame interpreter that uses frames as units.

By executing the man-machine rough 11ware at frame m, man-machine operations such as displaying the corresponding screen and executing processing can be confirmed.Furthermore, the man-machine software after completion also operates under the frame interpreter. .

FIG. 3 shows the concept of a frame. Data and procedures related to the 0 screen are accumulated in the system in units of frames.

FIG. 4 is an example of a frame data item defined through the frame manager according to the present method. Box 13 is data related to screen control, and when frame A is executed (displayed on the screen) by frame interpreter 12 in FIG. It represents the frame name and procedure name that are executed according to the corresponding code. The part in box 74 is data related to one-screen display, and the double-sided display procedure 72 is data necessary for one display.The zero-screen display procedure uses the frame interface routine to display the screen defined in frame A71. Access display-related data.

In this example, the screen display data includes 1 screen display item and 9 screen display position.

Data representing colors etc. is defined.

FIG. 5 is an operational flowchart of the frame interpreter that executes frames. The frame interpreter has a structure that refers to the description of the frame and determines the procedure to be executed.The basic execution cycle is a loop that repeats frame selection and execution according to the input to the frame interpreter. For example, when the frame interpreter executes the frame shown in FIG. 4, it first starts the screen display procedure 72. Launched screen display procedure 72
accesses the screen display data 74 described in frame A through the frame interface routine, and while the frame A71 that performs the corresponding screen display is displayed on the screen, a keystroke is performed from the terminal and the corresponding code is However, in the case of code 4, the frame interpreter starts the procedure corresponding to 1 procedure name a. If the corresponding code is code 3, the frame corresponding to frame name C is executed. Below is frame A71
It is the same as when is executed.

This embodiment uses a data structure called a frame to represent data and procedures related to each screen as a single unit. In addition, a frame manager is used as a means of handling frames.

A frame interpreter is provided.

According to this embodiment, since information such as data and modules related to one screen is managed in units of frames, it is possible to create a software structure in which it is very easy to add, change, and delete programs in units of screens. . Also, data for controlling the execution of the frame itself is written within the frame.

Frame in the part that controls frame execution,
Because it is prepared outside the frame as a interpreter,
It is possible to create a software structure in which execution control of the entire frame is less susceptible to changes or deletions of other frames.

【Effect of the invention〕

According to the present invention, it is possible to create a program that bundles screen-related data and procedures, and creates a software structure that is easily subject to change and that makes it easy to add, change, and delete programs related to screens. can do. In addition, this makes it easy to create programs step by step for each screen, which is effective in improving the productivity of man-machine software that involves screens, which tend to be complicated and bloated.
