Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] When text data in a data area larger than the display screen of the display is edited such as deleted or copied, the boundary information of the data area is left on the screen after moving the screen. ， Easy to operate.

[Industrial application field]

The present invention relates to a method of displaying a processing range in a data processing device having a screen editing function.

[Conventional technology]

Generally, in a display such as a CRT used in a data processing device, the amount of data that can be displayed at one time is limited to a relatively small amount. Therefore, it is possible to perform screen editing processing such as deletion or copying for a data area that exceeds the screen display area. When doing so, the screen display area must be moved to the required position for processing.

FIG. 7 shows an example thereof. In the figure, (a) shows the state before moving the screen, (b) shows the state after moving the screen,
In the figure, 1 is the text to be processed and 2, 2'is the screen of the display.

In FIG. 7 (a), when the line number 020 to 050 displayed in the screen 2 is to be moved and edited after the line number 120 in the area outside the screen 2, After marking the line range, the screen 2 is moved downward so that the line with line number 120 is displayed in the screen 2 ', as shown in FIG. The operation of moving and editing the line range of is performed. And in this case,
The line range marked earlier is outside the display range of the screen 2'of (b) and cannot be seen.

[Problems to be solved by the invention]

As described above, in the conventional screen editing process, when the text in the data area wider than the screen is targeted, in the editing process over the screen, all the ranges necessary for the process are simultaneously displayed in one screen. Can't see inside.

Therefore, the screen is moved, but at that time, if you want to reconfirm the mark of the processing range that has gone out of the screen, or if you want to change or cancel the mark, you must return the screen to that position. ， Cumbersome operation is required,
There was the problem of being inefficient.

[Means for solving problems]

According to the present invention, even when a line marked in the screen editing process is outside the display area of the screen due to the screen movement, the information of the marked line is displayed on a part of the screen after the movement, and after the movement. It is possible to perform necessary operations on the screen of.

FIG. 1 is a conceptual diagram showing the principle of the present invention. Note that (a) in the figure shows the state before the screen is moved, and (b) shows the state after the screen is moved. In the figure, 1 is text and 2, 2'is the screen of the display. Reference numeral 3 denotes a processing range targeted for deletion, movement, copying, etc., and marks (arrows in this example) are added to the upper and lower limit lines. Reference numeral 4 denotes processing range information displayed on the screen after the screen is moved, that is, display of lines marked with the processing range 3, and 5 denotes a command input area.

Mark the upper limit line 020 and the lower limit line 050 of the processing range 3 of the text 1 in the state of the screen 2 of FIG. 1 (a), and then move the screen to 2'of FIG. 1 (b). .

At this time, on the screen 2 ', two lines 020 and 050 marked on the screen 2 are displayed as processing range information at the top of the screen 2', just below the command input area 5 in the illustrated example.

When the screen 2 is moved upward to the outside of the processing range 3, the processing range information 4 is displayed at the bottom of the screen 2'and the screen 2 is moved up and down within the range of the processing range 3. In this case, only the mark lines at the upper or lower limit protruding from the screen 2 are displayed as the processing range information at the bottom or the top of the screen 2 ', and the remaining mark lines correspond to those in the screen 2'. The position is displayed normally.

[Action]

According to the present invention, the mark line indicating the set processing range is always displayed on a part of the screen after the movement regardless of the size of the text or the size of the screen movement, and only the screen after the movement is displayed. You can check, change, or cancel the processing range of the original screen.

〔Example〕

 FIG. 2 shows the configuration of one embodiment of the present invention.

In the figure, 10 is a display, 11 is a command input section, and 12
Is a processing range setting unit 13 is a screen movement processing unit, 14 is an editing processing unit,
15 is a screen memory, 16 is a data memory, 17 is a display controller, 111
Is a mark setting command, 112 is a screen move command, 113 is a delete command, 114 is a copy command, and 115 is a move command. Further, 151 is a line number, 152 is a sentence, and 153 is each area of a mark.

The data memory 16 stores data of the entire text to be processed.

The screen memory 15 stores the data currently displayed on the display 10. The data in the screen memory 15 is
It is cut out from the data memory 16 under the control of the screen movement processing unit 13 and displayed on the display 10 via the display control unit 17.

The command input unit 11 analyzes a command input along with the screen operation and the editing process, and activates a necessary processing unit.

The mark setting command 111 is used when inputting marks to the upper and lower limit lines that define the range of deletion, copying, moving, etc. in the editing process, and the mark information is used as the processing range setting section.
By 12, the data is written in the mark area 153 of the screen memory 15.

The screen move command 112 is used to move the text area displayed on the display 10 up and down.
According to the instruction content, the screen movement processing unit 13 stores the data for the screen based on the predetermined base point position in the data memory 16
Then, the contents of the screen memory 15 are updated. However, at this time, the data line where the mark is set first is
It is left at an appropriate position in the screen memory 15 according to the direction and size of the screen movement.

As a result, the line marked on the original screen according to the contents of the screen memory 15 is displayed on the display 10 after moving the screen. The details will be described later.

After that, when an edit processing command for the processing range defined by the previously marked line such as the delete command 113, the copy command 114, or the move command 115 is input, the edit processing unit 14 causes the screen memory 15 The processing range surrounded by the mark line is recognized, and the instructed editing process is executed on the data in the data memory 16.

The result of the editing process is reflected in the screen memory 15, and the screen display is also updated.

FIG. 3 shows a flow chart of the control procedure of the screen movement processing unit 13 of FIG. 2, and FIG. 4 shows a processing example thereof.

That is, the screen movement processing unit 13 checks the presence or absence of a mark in the mark area 153 of the screen memory 15 before moving the screen, and if there is a mark, if the line is included in the display range of the screen after movement, The mark line is displayed as it is mixed with the text like. FIG. 4 shows this by way of example, and shows the states of the screen memory 15, the data memory 16, and the display 10 in association with each other.

When the mark line does not exist in the display range of the screen after the movement and the mark line is smaller than the display range, the mark line is displayed at the top of the screen as in, and when the mark line is larger than Is displayed at the bottom of the screen. FIG. 4 shows an example in which both the upper and lower mark lines of the processing range are smaller than the display range, and one mark line is larger than the display range and the other is smaller.

Although a specific symbol such as an arrow is used as the mark, it is also possible to increase the brightness and adopt a highlighted display format. To cancel the set mark line, move the cursor to the mark line displayed on the screen and enter the reset (not shown) command. FIG. 5 is a flowchart showing the control procedure of the processing range setting unit 12 of FIG. In this example,
Marked lines are highlighted.

Also, instead of using a single symbol such as an arrow as a mark, by giving a unique name to each mark line and using this name to specify a specific mark line, it is possible to change the screen movement and editing processing range. It may be possible to make a call.

FIG. 6 is a conceptual illustration of this. In FIG. 6A, two processing ranges specified by mark 1 and mark 2 are set, and mark 1 is specified to perform search or replace. To do.

 Mark 2 is specified to search or replace.

The range of mark 1 or mark 2 is copied or moved to the position of target 1 or target 2.

Move the screen with mark 1 or mark 2 as the base point of the screen.

Can be processed.

FIG. 6 (b) shows mark 1, mark 2, mark 3, mark 4
Set the mark line of and mark 4 on the mark 1 screen.
In this example, the screen is moved by specifying, that is, by inputting the "FIND MARK 4" command.

〔The invention's effect〕

According to the present invention, the marked line that defines the edit processing range on the text is always left on the display screen regardless of the screen movement. Therefore, when changing or canceling the marking, the line is executed without moving the screen. It is possible, and when performing edit processing involving screen movement on arbitrary text that is larger than the display screen, there is almost no need to return the screen after movement to the original screen, and the size of the display screen is restricted. Nevertheless, the editing process can be performed efficiently, and the operability can be significantly improved.
