Abstract

PURPOSE:To display an operating procedure corresponding to misoperation when the misoperation takes place so that the proper procedure can be recognized by the operator, by providing an RAM equipped with a line memory and error informations storing register, video RAM, etc. CONSTITUTION:When misoperation takes place and an operator knows the misoperation through a buzzer AL or display on a CRT, he depressed a key 'HELP' on a keyboard KBD. Then the 'HELP' key is depressed, the display data on the 25th line of a video RAM VRAM are transferred to a line memory SAVE 1 in an RAM. Then an error information storing register ERRCD in the RAM is read out and an explaining sentence and operating method corre sponding to the numerical value of the register ERRCD are read out from a floppy disk. The read out content is transferred to an stored in the RAM. Thereafter, the stored content is written on the 25th line of the VRAM and displayed in the CRT through a CRT display controller CRTC. Therefore, when misoperation takes place, an operating procedure corresponding to the misoperation can be displayed.

Description

[Detailed Description of the Invention] [Description of the Prior Art] Conventionally, most word processors have a "HELP function" that displays operating procedures or function explanations on a CRT display in response to the press of a specific key. It had a function. The above-mentioned "I (ELF function)" is a method that displays a pre-prepared explanatory text from the beginning in response to the press of a specific key, or a method that corresponds to the press of a specific key followed by the press of a second specific key. There is a system that displays each function explanation or operation method on a CRT display.However, the "HELP function" of the above system is
is merely an electronic representation of the Operator's Handbook. This conventional technique will be specifically explained below. As shown in Figure 1, a word processor consists of a keyboard, a processing section floppy disk, a CR
It consists of a T-display, a pre-printer, etc., and its keyboard is equipped with the same arrow keys as a typewriter keyboard, as well as cursor keys and function keys (such as ``CENTER'') specific to word processors, as shown in Figure 2. Normally, e:tS3 is a diagram showing the HELPa function according to the prior art related to the present invention. In response to pressing the "HELP" key, a large explanatory text or operation method is displayed on the CRT display for the first time. This shows the method for displaying from

Therefore, the information that had been displayed until then disappeared. Similarly to FIG. 3, FIG. 4 also shows the "HELP"
This indicates the age of the machine.When the key ``HELP'' is pressed, a large explanatory text similar to that shown in Figure 3 is displayed from the beginning, and then when the key ``CENTER'' is pressed, an intermediate explanatory text is displayed. This shows a method of skipping the centering 411 function and displaying an explanatory text or operation method for the centering 411 function.In both of the methods shown in FIG. 3 and FIG.
It is just a large explanatory text or operating instructions on the RT display, so that when the operator is operating the word processor, it is easy to use according to the situation.
It is not a 'HELP function', so I would like to use the HELP function.I am always forced to interrupt the operation once for the HELP function.Furthermore, I have to re-enter the character string related to the operation error. Ta.

〔the purpose〕

This invention is! An object of the present invention is to provide a character processing device that displays an operation procedure corresponding to a J14 operation when a J14 operation is performed.

[Detailed explanation]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 is a diagram to clarify the application of the present invention, that is, a word processor. In the figure, CFIT is a CRT display device, BDY is a device incorporating a processing device and a flop disk drive, etc., FDD-A, FDD-B.

connected with. In other words, each device is controlled by the microprocessor CPυ. More specifically, to explain the operation of each device, when the power is turned on, the microprocessor CPU executes a floppy disk controller FDC, a CRT display controller CR, according to a fixedly built-in program in the read-on memory ROM.

Measures initialization. In other words, it creates the appropriate conditions for the device to operate. 7, 10, and 11 according to an embodiment of the present invention and programs necessary for word processing processing from the floppy disk drive AFDD-A.

The programs shown in the flowcharts of FIGS. 12, 14, 15, 16, and 17 are read out and stored in the program memory PM in the random access memory RAM. In this state, there is no need to program the read-on memory ROM, and the flow of control shifts to the program stored in the program memory PM in the random access memory RAM. As is clear here, the capacity of the random access memory RAM is larger than the capacity of the read-on memory ROM, and the capacity of the program memory PM is required to correspond to the program size required for word processing.

For example, 128 bytes. Read-on memory ROM
requires a capacity corresponding to the size of the program required to start up the word processor, for example 8 bytes.

The word processor program stored in the program memory PM is used to control each device as needed. The floppy disk controller FDC receives instructions from the microprocessor and transfers or receives data to the floppy disk drive FDD.The CRT display controller CRTC includes a character generator storing character fonts and receives instructions from the microprocessor CPU. Video RAM VRAM with reference to text memory SM! :Work together to display characters or figures on a CRT display. The video RAM VRAM corresponds to the dots of the CRT display and can store bit information, and since the CRT display is 640 dots horizontally and 400 dots vertically, it is 640x4.
00 or 256 bytes) (32 bytes) is required. Furthermore, since the video RAM VRAM is directly connected to the common bus CBUS, each bit can be arbitrarily manipulated by the microprocessor CPU.

This means that you can use any putter 7 without being aware of the character shapes.
It is convenient for controlling the

Keyboard controller KBC and microprocessor C
It can be directly controlled from the PU, and can inform the microprocessor CPU which key is pressed. The asynchronous communication controller UART is also controlled by f# from the microprocessor CPU and sends print information to the printer PRT.
used to send to. The programmable timer TIMMER can also be controlled by the microprocessor CPU and can monitor any time. Utilizing this fact, the ringing time of the Bude AL is also controlled.

Now, the present invention utilizes the above-mentioned hardware more effectively. Therefore, the following explanation will be given based on an example of an operation performed by an operator. FIG. 7 is a flowchart showing the correct operating procedure for the centering function according to this embodiment. The centering function here is a function that automatically positions the character string in the middle of the apex of the left margin and right margin. First, in step 7.1, position the cursor on a blank line (a line with no characters) and press the key "CENTE".
Press “R”.

At this time, the centering a function mark is displayed on the line where the cursor is located, indicating that the following character strings will be centered.Next, enter the centering S character string in slap 7.2, and press the key in step 7.3. ″RETU
When you press RN'', the character string is positioned and displayed in the middle of the left and right margins. This is the correct operating procedure.

However, if the input includes an incorrect operation procedure as shown in 1J8TI4, the following will occur in the embodiment of the present invention. First, as an operational background, assume that after completing input for one page, the operator realizes that the character string to be centered must be inserted backwards or upwards.

Then, in step 8.1, the operator positions the cursor at the desired position using the cursor movement keys and presses the ``IN'' key.
Press "S" to instruct to insert a blank line. Then, a blank line will be created.

Insertion of a character string is now possible and the character string to be centered is entered first without accidentally pressing the key "CENTER" in step 8.2. CRT at this time
The display CRT is displayed as shown in Figure 9(a). In Figure 0, the character string that has already been input is displayed after "WORD", and the character string "CENTERING" is displayed.
” is an intervening string of characters. Therefore, the cursor is set to the character “
It is positioned immediately after the character string “NE
XT" and below shows the last line on the CRT display. The λ theory will be a little more detailed here, but in this example, C
As mentioned above, the number of dots displayed on the RT display is 640×400, that is, 256,000 dots, and one character is assigned 8 dots horizontally×16 dots vertically (see FIG. 13).

As a result, *aSO characters, 25 vertical characters, can be displayed. Therefore, in FIG. 9(a), the character string “WO
RD” is the first line, the character string “(:ENTER” is WIJ
On the 24th line, the character string "NEXT" is displayed on the 25th line. Here, the 25th line is treated in a slightly special way, and is programmed to actually prohibit positioning of the cursor or the like. The means for this prohibition is to refer to the row register of the two registers, the row register and the column register, for knowing the current position of the cursor defined on the CRTC.
When you want to move to the next row, you can do so by scrolling up the display contents on the CRT display. 1st theta
The figure below is a flowchart showing this, assuming step 11.
．． When the cursor down key is pressed in ■, step 1
In step 1.2, it is determined whether the contents of the row register LR are the numerical value "24" or not. If the numerical value is "24", the contents of the video ram VRAM are changed to 13 for screen scrolling in step 11.3. By writing the dot data on the first line to the first line, moving the dot data on the third line to the second line, and performing this transfer over all lines, the CRT
As the first processing that can make it appear as if scrolling on the display CRT, if the 25th line already exists on the document memo 95M, it is read out and the dot data of the 25th line is transferred to the video ram VRAM. If the 25th line does not exist on the document memo 95M, the entire 25th line of the video RAM VRAM may be cleared as blank information.

On the other hand, if the line register is not at the 24th line in step 11.2, the cursor is automatically moved downward by adding ``+1'' to the line register LR% in the CRT display control roller CRTC. In this way, the above-mentioned prohibited moves allow the operator to perform operations while checking the front and back of the document.

Now, returning to the second theory in Figure 8, the operator tries to center the character string "CENTERING" that has been inputted between the left and right margins, and in step 8.3 the key "CENTERING" is
At this time, as shown in FIG. 11, in step 12.1, it is determined whether a character string exists in the line corresponding to the value of the line register LH in the CRT display controller CRTC. Check on Document Memo 95M.

If the string exists.

Since this is an operational error, the flow of control continues to step 12.
Move to 2 and set the programmable tieboo TIMER to 500m.
Set 5ec. As a result, the buzzer AL starts sounding. Subsequently, all bit information corresponding to the 25th row of the video RAM VRAM is inverted. In other words, “0” becomes “1”.
1" is set to "0". As a result, along with the buzzer AL sounding, the 25th line 0 of the CRT display is reversed black and white, and after 500m5ec, the program pull timer TIME is set.
R will stop automatically. Therefore, the buzzer AL will stop ringing. This state is shown in FIG. 9(b).

Then, in step 12.4, the error information storage register ERR is
Write the number "3" on the CD as a centering operation layer to store the information for subsequent control.

Now, returning to the discussion in Figure 8, the buzzer AL or CRT
If the operator notices an error in the operation on the display CRT, press the key °“HE” on the keyboard K1111 in step 8.4.
Press LP”.The CRT displayed at this time
The display CRT screen is shown in FIG. 9(C), in which the 25th line displays an explanation of centering and an operating method. This screen can be created as follows. Figure 12 is fjIJ8rI! FIG. 8 is a diagram showing internal processing corresponding to the pressing of the key "HELP" in step 8.4 of J. In step 4.1 key "HEL"
When it is determined that "P" has been pressed, control moves to step 14.2.
Here, the display data on the 25th line of the video RAM VRAM is stored in a predefined random access memory RAM.
All data are transferred to the upper area line memory 5AVEI. This line memory 5AVE l is 16 bytes x 80 digits = 12
80 bytes is sufficient because each character consists of 16 bytes as shown in FIG. 13 for one digit character.

Up to the next control step 14.3, the ERRCD, which has already been stored as ERROR information, is read in preparation for the next processing step 14.4. Step 77'14.4j: +r
The explanatory text and operating instructions corresponding to ``3'' are read from the floppy disk, transferred to an unused area of the random access memory RAM, and stored. In addition, in accordance with the value of ERRCD, the explanatory text and operating method of "rearrangement", movement, and other functions are read out.Next, in step 14.5, the explanatory text and operating method that have just been stored in the random access memory RAM are displayed in the video. Of course, the explanatory text stored in the random access memory RAM is written to the 25th line of the RAM VRAM via the CRT display controller CRTC, and each character is a 1-byte character code. On the video RAM VRAM, each character is a 16-byte character font.

As described above, upon completion of 14.5, the control enters a key wait state. As can be seen from FIG. 14, the three keys that are permitted are: ``HELP゛° 0→''←゛. When the key "←" is pressed, the video ram VRAM 25 is
Scroll the row to the left. Next, the following explanatory text and operation method information are taken out from the random access memory RAM containing one character and placed in the 25th line 8 of the video RAM AVRAM.
At the same time as writing tJ into column 0, a cursor is displayed in column 80 using the method described above. On the other hand, for the key "←", as shown in step 18.1 in Figure i15, the 25th row of the video ram VRAM is horizontally scrolled to the right and the information of the 25th row and 1st column is retrieved from the random access memory RAM. It is written in the 25th row and l column of the video RAM VRAM, and in this way, left and right scrolling of only the 25th row is performed. In addition, when the key "HELP" is pressed, the process shown in FIG. 2812 is skipped.

Now, returning the discussion to Figure 5!8, once the operator understands the operation method related to centering by calling the explanatory text and operation method described above, in step 8.5, press the key “HEL”.
Press "P" again. At this time, the line where the cursor is located disappears from the screen as shown in Figure 0 (Figure 9(d)).

The 25th line reproduces the next line of the input document.

This screen is created as follows. FIG. 16 shows this. Step 8.5 in Step 19.1
At the same time, that is, when the key "HELP" is pressed, the character string "CENTERING" appears on the cursor line, that is, the 24th line.
are all transferred to the storage area line memory 5AVE2 on the RAM and stored therein. The line memory 5AVE2 may have a size of 80 bytes, which means that 80 characters per line are stored as character codes, so the capacity is for one line. Returning to FIG. 16, in step 19.2 all cursor lines on the video RAM VRAM are erased. As a result, the line where the cursor is located on the screen, that is, the cursor line, becomes a blank line. Then move the cursor to the first column of the cursor line.
Then, in step 19.3, all character patterns of the next line already stored in the line memory 5AVEI on the random access memory RAM are transferred to the video RAM VRAMIJ.
The 25th line is inverted and written, where "5AVE1°" stores the inverted information as described above.

The above results, explanatory text, etc. are the information in the line memory 5AVEl. The next line will be displayed again. Returning the discussion to FIG. 8 again, if the operator presses the key 'CE N T E R' as a correct operation in step 86, the screen becomes as shown in FIG. 9(e), where the key 'CEN
Since the device has recorded "TER", the center rig function mark "0 cow" is displayed. After this, either input the centering character string from the keyboard or press the key "RECALL", which is one of the features of the present invention.
Here the key "RE CA L" according to Figure 8.8.7
If you press ``L'', the llli surface will be as shown in Figure 9 (f
), that is, a character string entered with an operational error can be used again. This is done by the following control. The character string stored in the line memory 5AVE2 on the random access memory RAM can be transferred so that it is displayed after the cursor on the cursor line.If it is input correctly in this way, then the operation When the person presses the key "RETURN" in step 8.8, the character string "CENTERING" is centered, the cursor moves to the beginning of the next line, and the entire screen is scrolled up as shown in Figure 9 (g). Ru. This scroll is the video ram VRA as mentioned above.
For the information of M, the second line is transferred to the first line, the third line is transferred to the second line, and the same transfer is continued, and the 25th line is transferred to 24
Transfer to line 1.

When the process is finished, a new line may be displayed on the 25th line by referring to the document memory SM.

In addition, in step 19.3 of Fig. 16, the video ram VRAM
To! I! Whether or not to store 1 inverted when storing 1, that is, line memory 5A on random access memory RAM
VE 1 needs to determine whether or not inversion information is stored, and this is done using the following method. 13th
As shown in the figure, the hatched bits are bits to create gaps between characters, and if they are inverted, they are logical.
It is set to ``l'' and remains logic ``0'' unless it is inverted. Therefore, by determining the most significant bit of the first byte of each character, there is no need to provide a special flag, and it is very easy to use. This is an effective method.

[Other Examples] In the above explanation, the explanation and operation method for the HELP function was about centering, but other functions such as data sorting, searching, etc. may also be used. However, other storage devices such as a hard disk or RAM may also be used.

In addition, although the highlighted display at the time of the "l" operation was set to the lowest row, it may be any row.

〔effect〕

As described above, according to the present invention, the operating procedure corresponding to the erroneous operation is called up and displayed, so that the correct operating procedure can be recognized without interrupting the operator's thinking. That is, the user does not have to skip unrelated explanatory sentences until the desired explanatory sentence is displayed, as in the conventional case.
