Description

[Detailed Description of the Invention] [Summary] Regarding the processing of so-called program function keys for specifying processing from a computer terminal device, a program function is provided that allows easy modification of the correspondence between application program processing and program function keys. For the purpose of a key processing method, a computer having an application program for executing a process assigned to a terminal device having one or more keys when the press of the key is detected. A correspondence table showing the correspondence between the logical attention signal unique to each process and the code of the key to which the process is assigned, and the code generated by pressing the key are used to index the correspondence table and correspond to the code. means for determining the logic attention signal to be sent and notifying the application program, and the application program is configured to execute a process determined by the notified logic attention signal.

[Industrial application field]

The present invention relates to the processing of so-called program function keys (hereinafter referred to as PF plain keys) for specifying processing from a terminal device of a computer.

[Prior art and problems to be solved by the invention] FIG. 4 is a block diagram showing an example of the configuration of a computer, in which the codes of each key generated and transferred by pressing a key on the keyboard of the terminal device 1. is received by the input/output control unit 2 and passed to the application program 3.

For example, if the application program 3 is in a state of waiting for data for a certain process, it processes the passed code as data, and if it is in a state of waiting for a process to be designated, it processes the PF using that code.
It identifies one type of flat key and starts the process assigned to the key.

FIG. 5 shows the flow of processing when an input coat is received while waiting for processing to be specified, and the manual code is determined as in processing step 10 and processing step 11, and the corresponding processing A and B are performed.
, branches to -N, and if none of the planned PF plain keys is selected,
For example, processing such as displaying a message on the terminal prompting the user to re-enter the input information is performed in response to an input error.

The assignment of the PF flat key to a certain process in such applications often requires changes due to the relationship with the processes of other application programs, the familiarity of the terminal user's operations, etc.

On the other hand, as shown in FIG. 5, programs for identifying PF plain keys and starting required processing are scattered throughout the application program 3, so when changing the correspondence between processing and PF plain keys, it is necessary to Since it is necessary to examine the entire program and modify the necessary parts, there is a problem that modification is time-consuming and errors such as omission of modifications are likely to occur.

The object of the present invention is to provide a program function key processing method that facilitates processing of application programs and changing the correspondence between PF plain keys.

[Failure to solve the problem]

FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of the computer, and 20 is a correspondence table 2 according to the key code that is received from the terminal device 1 via the input/output control section 2.
1 is a conversion control unit that searches for and converts the logical attention signal to the application program 22, and the application program 2
2 is configured to identify processing by a logical attention signal.

[For production]

The application program 22 generates a unique logical attention for each process in order to execute a process assigned to a key of the terminal device 1 having one or more keys when the press of the key is detected. Receives from the input/output control unit 2 a correspondence table 21 showing the correspondence between signals and codes of keys to which each process is assigned, and codes generated by pressing those keys, and indexes the correspondence table 21 using the codes. A conversion control unit 20 is provided which is a means for determining a logical attention signal corresponding to the code and notifying the application program 22 of the determined logical attention signal. The application program 22 is configured to execute processing determined by the notified logical attention signal.

With this processing method, the assignment of keys to processes can be changed by changing only the correspondence table without modifying the internals of the application program.

〔Example〕

As in the conventional example, the PF plain key is used as the key for specifying the processing of the application program, and the correspondence table 21 in FIG. 1 is, for example, as illustrated in FIG.
The control information is in a tabular format consisting of pairs of each PF flat key code and each name defined as a logical attention signal.

In the illustrated part, for example, a logical attention signal for specifying upward scrolling of the screen is rUPJ, a logical attention signal for specifying downward scrolling is rDOWN, and the codes for these are FOO7 in hexadecimal representation. An example of assigning PF keys to FOO8 and FOO8 is shown.

As in the past, the code of the key pressed on the terminal device 1 is
When the conversion control unit 20 receives the data through the input/output control unit 2, the PF is processed in a processing step 30 as shown in FIG.
A primary key code is identified, and if there is a PF primary key, a processing step 31 indexes the correspondence table 21 based on the code, reads out a corresponding logical attention signal, and passes this signal to the application program 22 in a processing step 32. Also, PF
If it is not the primary key code, the input code is passed as is to the application program 22 in processing step 33.

Correspondingly, the program waiting for process designation in the application program 22 determines the logical attention signal as in process step 40 and process step 41 as shown in FIG. , B, -N, and if none of the planned logical attention signals is present, a message prompting re-input is issued, for example.

In this way, the application program 22 determines the process based on the logical attention signal, so when changing the PF primary key assignment, change the correspondence with the PF primary key logical attention signal in the correspondence table 21, so that the same process is always the same. By specifying the logical attention signal, there is no need to modify programs such as those shown in FIG. 3(b) that are scattered throughout the application program 22.

In the above explanation, one correspondence table 21 was used for the application program 22, but two or more types of correspondence tables may be provided for one application program so that the conversion control unit 20 can input a predetermined designation input by the user. By identifying them, it is possible to select the correspondence table to be used, and for example, it is also possible to change the PF primary key assignment for each user group.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is easy to change the so-called PF primary key correspondence for specifying processing from a terminal device in a computer, and to assign appropriate keys to the user. This has a significant industrial effect.
