Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic screen file selection method, and more particularly to an automatic screen file selection method used in connection with a screen display function in an information processing system operated in the TSS method. .

[Conventional technology]

As shown in FIG. 3, conventionally, the screen display processing on the display type terminal device in the TSS type information processing system is performed by the screen display function section 8 using the screen identification information passed from the user program 7 as a key to the source library. This is done by extracting either the screen source or the screen object from the screen object library 11 or the screen object library 10, converting it into screen data that can be sent to the terminal, and sending it to the display type terminal device 9.

Here, the screen identification information is key information from which a screen source or screen object in a file can be read, and is uniquely determined within each file. Further, generally, if the screen is the same, the screen source and screen object have the same screen identification information.

[Problem that the invention seeks to solve]

The conventional screen display function described above simply retrieves pre-specified screen image data from each storage medium, converts it into screen data, and sends it to a display terminal device. It is necessary to limit the image data to either a screen object or a screen source, or to notify the type of screen image data from the user program, which has the disadvantage of low operability of the user program. be.

[Means for solving problems]

The screen file automatic selection method of the present invention includes a file information acquisition means for acquiring management information of a file in which screen image data is stored, in order to know whether the screen image data prepared by the user is a screen object or a screen source. , a file format determination means that determines the file format based on the acquired file information; a screen object reading means that reads the screen object if the file format is a screen object library or an integrated library; If it is a library, it has screen source reading means for reading the screen source.

[Effect]

The file format is automatically determined based on the file information, so the screen image data prepared by the user can be saved as either a screen object or a screen source.
There is no need to limit the type of screen image data or to have the user program notify the type of screen image data.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the screen file automatic selection method of the present invention, and FIG. 2 is a flowchart showing details of its operation.

The screen file automatic selection section 1 of this embodiment is used by being connected to the screen display function section 8, and includes a main control section 2, a file information acquisition section 3, a file format judgment section 4, a screen object reading section 5, and a screen source reading section. It consists of 6. Screen display function section 8
receives the screen identification information of the screen to be displayed from the user program 7, and uses this as a key to store the screen object in the screen object library 10.
This is a conventional screen display function unit that either takes out the screen source from the source library 11 or takes out the screen source from the source library 11, converts it into screen data, and then sends it to the display type terminal device 9. If the section is connected, control is passed from the user program 7, and then control is passed to the screen file automatic selection section 1 together with screen identification information. Here, the screen identification information is
This is key information that can read the screen source or screen object in the file, and is uniquely determined within each file. Further, generally, if the screen is the same, the screen source and screen object have the same screen identification information. The file information acquisition unit 3 acquires file management information from the file management area existing on the medium, and the file format determination unit 4 determines the file format from the acquired file management information to create a screen image. This is the part that specifies the type of data. The screen object reading unit 5 reads the screen object library 1 using the screen identification information as a key.
0 or the integrated library 12, the screen source reading unit 6 uses the screen identification information as a key to read the screen object from the source library 1.
1 or the integrated library 12. The main control section 2 is a control section that controls these.

The screen object library 10 is a file that stores only screen objects, the source library 11 is a file that can store screen sources, and the integrated library 12 is a file that can store both formats.

Next, the operation of this embodiment will be explained with reference to FIG. When control is passed from the screen display function section 8,
The file information acquisition section 3 opens the specified file and extracts the management information of the file from the management area on the medium (step 21). Based on this file management information, the file format determining section 4 determines whether the file format is a screen object library, a source library, or an integrated library (step 22). If the specified file is a screen object library or an integrated library, the screen object is loaded (step 23), and if it is a source library, the screen source is loaded (step 26).
However, when loading the screen object, there is no screen object with the screen identification information passed from the user program in steps 24 and 25.
Also, if the target file is an integrated library, the screen source is read (step 26).
Determine if screen source exists (step
27) If the screen object or screen source has been successfully read, control is returned to the screen display function section 8 together with these screen image data.

〔Effect of the invention〕

As explained above, the present invention automatically determines whether the screen image data is a screen object or a screen source based on the file format when reading the screen image data that is input to the screen display function from the storage file. By doing so, there is no need for the user program to specify the type of screen image data or for the user program to notify the type of screen image data, so the user program does not have to worry about the type of screen image data used. This has the effect of significantly increasing the operability of user programs.
