Abstract

PURPOSE:To use a display area for guidance even by an applied program by saving display data before an input an input character string and the guidance are displayed, redisplaying the saved data before characters of the applied program are displayed, and erasing the input character string and guidance display. CONSTITUTION:When the applied program 10 starts input processing, a display data saving means 12 saves the display data and after an input state display means 13 displays the input character string and guidance, the input processing 14 is performed. When the program 10 starts display processing, a redisplay means 15 redisplays the save display data and erases the input character string and guidance display and then the specified display processing 16 is performed. Consequently, one system line need not be defined for the guidance indicating an input state and the applied program can use larger display size.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer that can display and edit data input from an input device on a display device.

[Prior Art] Conventionally, in computers and the like capable of Japanese input, a guidance display for indicating information regarding the input state has been displayed on the bottom line or the top line of the display screen.

In addition, the input string was displayed on the same line as the guidance display or at the current cursor position for editing.

[Problem to be Solved by the Invention] However, in the above-mentioned conventional technology, the lines used for guidance display cannot be used in the user's application program, and the display size that can be used by the application program is reduced. There were drawbacks.

Furthermore, when displaying an input character string at the current cursor position, there is a drawback that if an application program attempts to display the input character string while it is being displayed, the input character string cannot be displayed correctly.

The present invention solves the above-mentioned problems of the prior art, allows the display area for displaying guidance to be used by application programs, and allows normal display in application programs even when input character strings are displayed. The purpose is to provide a computer that can be used.

After the system starts up, follow the operator's instructions and input from the keyboard (34) to save the external memory bag! Program from (33) to RAM
(32) and start it.

The operation of Japanese input processing in this embodiment will be explained below.

FIG. 4 is a flowchart showing the operation of the input processing routine.

First, the symbols used will be explained.

KBUF1 is a buffer that stores a character string determined by converting data input from the keyboard (34) into kana-kanji.

KBUF2 is a buffer that stores undefined character strings that are input from the keyboard (34).

C0UNT is a timer for measuring the elapsed time since the display processing routine was last activated.The initial value is set in the display processing routine, and is subtracted every time a timer interrupt occurs, and the time is counted until it reaches 0.

FLAG is a flag indicating whether or not the display data has been saved; 0 indicates that it has not been saved, and 1 indicates that it has been saved.

KBUFI, KBUF2, C0UNT and FLAG are in RAM (32).

Now, when the input processing routine shown in Fig. 4 is activated, it first checks KBUFI (S401), and if there is confirmed input data, extracts one character from KBUF1 (5415), and selects r people. It ends with "Yes" status.
If there is no confirmed data in KBUFl (3402
) and (S403) cOUNT and FLAG (7
) value. If the value of C0UNT is O and the flag has been reset to 0, save the display data (5404), display guidance (S405), and
Display undefined character string in BUF2 (S406)
FLAG is set to 1 (S407).

Next, it is checked whether there is any input from the keyboard (34) (S408), and if there is no input, the process ends with "no input" status. If there is an input, check whether the input key is a confirmed key (S409). If it is not a confirmed key, set it to KBUF2. After performing kanji conversion,
It is displayed on the display device (35) (5410) and ends with "no input" status.

In (S409), if the input key is a confirmed key, check whether there is data in KBUF2 (S4
11) If there is no key, the process will end with "no key personnel",
If there is, copy the data in KBUF2 to KBUFI (S412), redisplay the saved display data (8413), reset FLAG to O (S414), and then extract one character from KBUF2 (S415).
The process ends with "key personnel available".

FIG. 5 is a flowchart showing the operation of the display processing routine.

The starting positions of the display processing routine are (E500) and (E
501) When called from a general application program, it starts from (E500), and when called from an input processing routine, it starts from (E501).

- When called from a g application program, first F

502), reset FLAG to 0 (S503) L,,
After setting the COUNT(7) value to 20 (S504), the instructed display operation is performed (8505). If FLAG is reset to 0, set the value of C0UNT to 20.
(3504) L, the instructed display operation is performed (S505).

On the other hand, when calling the display processing routine from the input processing routine, it starts from (E501), and then (S505)
Performs only display operations.

FIG. 6 is a flowchart showing the operation of the timer interrupt routine.

The timer interrupt handling routine is started by a hardware interrupt and first sets C0UNT (S
601), and if C0UNT is not o, decrement CoUNT by 1 (S602). If COUNT is O, nothing is done.

FIG. 7 is an example of an application program for explaining the operation of the computer of the present invention.

This application program is a program that outputs a character string including kana and kanji input from the keyboard to a communication line, and at the same time displays a character string received from the communication line.

When this application program is started, it first calls an input processing routine (5701), checks whether there is any input from the keyboard (8702), and if there is input, transmits the input data to the communication line (S703).

Next, a reception processing routine is activated (5704), the presence or absence of received data is checked (S705), and if there is received data, the received data is displayed (S706).

After executing the above processing, the process returns to (3701) and the above processing is repeated.

Now, in (S701), if characters have already been input from the keyboard and the confirmation key has not been pressed yet, the input f character string and guidance are displayed on the display device, but they have not been confirmed yet. Therefore, the input process returns with "no input from the keyboard" (S704).
).

Here, if there is received data, display processing (S706) is performed. At this time, since the character string and guidance input from the keyboard are displayed, in the display process, the display data is returned to its original state to erase these displays, and then the received data is displayed. On the other hand, the character string and guidance input from the keyboard are redisplayed when the input process (S701) is called after CoUNT time has elapsed since the last received data was displayed in the display process (8706).

Therefore, the received data can be displayed even when the undefined character string is displayed on the display device. In addition, by displaying the character string input from the keyboard and the guidance again after the CoUNT time has elapsed, it is possible to save the display data when it is being received intermittently from the communication line, and to redisplay the character string input from the keyboard. It is possible to omit a series of processes such as displaying guidance and redisplaying displayed data, and to continuously display received data with the character string input from the keyboard and the guidance displayed erased.

Note that although the above embodiment is for a computer capable of inputting Japanese, similar effects can be obtained with computers having other input character string editing functions.

FIG. 3 is a diagram showing an application program.

[Effect of the Invention I As described above, according to the present invention, it is not necessary to define one system line for guidance to indicate the input state, and the application program can use a correspondingly larger number of display sizes. Can be done. Furthermore, even if the input character string is displayed during input, it can be freely displayed on the display device from the application program.
