Description

Description: TECHNICAL FIELD The present invention relates to a target range specifying method for specifying a target range of an editing process in an information processing apparatus.

[Conventional technology]

2. Description of the Related Art Conventionally, there is a type in which a starting point and an ending point of a processing target are designated by a cursor, and various editing processes are performed in a designated predetermined range.

And when shading a predetermined character string, conventionally, move the cursor to the starting point of the character string to be shaded, press the shading key, and then move the cursor to the end point of the character string and press the shading key. The range of the character string to be shaded is determined.

Similarly, when shading a rectangular target range, first, a diagonal designation key is pressed to enter a diagonal designation mode for designating a rectangular range. Next, position the cursor at the upper left point of the shaded rectangle, press the shaded key, position the cursor at the lower right point of the shaded rectangle, press the shaded key, and The target range is determined.

As described above, conventionally, when an attribute such as shading is assigned by specifying a range to a character string, four operations are required.

[Problems to be solved by the invention]

As described above, when an attribute such as shading is assigned to a character string by specifying a range, each operation requires four operations, the number of operations is large, and the operability is poor.

An object of the present invention is to reduce the number of operations when assigning an attribute such as shading by designating a target range to a character string, and to specify a target range with fewer operation steps even in the case of specifying a rectangle, An object of the present invention is to provide a method of specifying a target range that improves the operability of document creation.

[Means for solving the problem]

The object is to provide a target range specifying method of displaying a character string input from a keyboard on a display screen and specifying a target for performing a desired editing process on a predetermined character string displayed on the display screen. As a first operation, a desired editing process is designated while the cursor is positioned at the first character of the target range, and as a second operation, the cursor is moved to the end point of the target range, and thereafter, in units of characters or lines. Alternatively, by specifying one of the diagonals, the target range of the character string to be subjected to the editing process specified above is specified, and the character string designated as the target range is shaded as a third operation. And so on.

[Action]

The cursor position at the time when the function key of the input means is pressed is set as the starting point, the cursor is moved to the end point of the target range, and then one of the options for selecting the target range displayed on the display screen. By selecting one, the target range of the character string to be subjected to the editing process specified above is specified, so that the number of operation steps for specifying the target range is reduced.

〔Example〕

Hereinafter, an embodiment of the configuration and method of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a document creation system for a Japanese word processor.

In the drawings, 1 is an input device such as a keyboard, and 2 is a CR.
A display device such as T, 3 is a document editing / proofing means, 4 is a position designation means, and 5 is a target range selection means.

 FIG. 7 shows a key arrangement of the keyboard 1.

Hereinafter, the processing of the document editing and proofreading means 3 will be described in relation to various keys of the keyboard and the flowchart of FIG.

Reference numeral 30 denotes a key input step. When the input key is the 'shaded' key (press the 'underline' key 110 while holding down the '★' key 111), press '<shaded>' to indicate that the shading function is being performed. A display is made as shown at 22 in FIG. 6B, a target range is specified by calling the subroutine SET @ OBJ, and a hatching process is performed by calling the subroutine BRUSH (32, 33, 34).

The same applies to other editing and proofreading functions such as underlining, character conversion, copying, moving, and deleting.

If the input key is one of the keys 112, 113, 114, and 115 related to the movement of the cursor 21 shown in FIG. 6A, cursor movement processing is performed (35).

If the input key is the "end" key 117, the editing and proofreading process ends (36).

If the input key is not the "end" key 117, the key input is performed again to perform the next process.

FIG. 3 shows a flowchart of the subroutine SET @ OBJ for specifying the target range.

In this subroutine, the cursor line position and column position are stored in variables SLINE and SCLMN, respectively, in order to use the cursor position when a function key indicating a function such as the 'shaded' key is pressed as the starting point of target specification. (330, 331).

Next, to indicate that the starting point has been specified, use SLINE
The character at the line and SCLMN digit position is displayed in black and white reversed (332), the subroutine SET @ END is called, and the end point is specified and the target range is selected (333).

Subroutine to set the end point of target specification and range of target range
Fig. 4 is a flowchart of SET @ END.

First, as shown in FIG. 6B, options for selecting a target range are displayed on the matrix 23 (3330). As options, character unit specification 231 to be the character from the character of the start point to the character of the end point, line unit specification 232 to be the line from the line of the start point to the line of the end point, diagonal the position of the start point and the position of the end point It consists of a diagonal designation 233 to be a character in a rectangle.

These choices correspond to the numeric keypad 1 to 9 keys, and the character unit designation is '7' key 107 or '8' key 1
08 or '9' key 109 is input, line unit specification is '4' key 104 or '5' key 105 or '6' key 106, and diagonal specification is '1' It can be specified by inputting the key 101, the '2' key 102, or the '3' key 103.

Next, the operation guide 24 is displayed as shown in FIG. 6B (333
1) Perform key input (3332).

After the key input, set the cursor line position and column position to the variables ELINE and E to set the current cursor position as the end point.
It is stored in CLMN (3333).

 Next, the input key is determined.

If the input key is the '7' key 107, or the '8' key 108, or the '9' key 109, it is specified in units of characters. Therefore, the variable R @ KIND storing the selection result of the target range is set to "0" (in units of characters). SLINE) that is the target of the operation
Inverts the character string from line, SCLMN characters to ELINE line, ECLMN characters (3334, 3338).

If the input key is the '4' key 104, or the '5' key 105, or the '6' key 106, the line unit is specified, so the variable R ￥ KIND for storing the selection result of the target range is '1' (line unit specification). Is stored, and the SLINE that is the target of the operation
Invert the line from the line to the ELINE line (3335, 333
9).

If the input key is the '1' key 101, or the '2' key 102, or the '3' key 103, it is a diagonal designation, so the variable R ￥ KIND for storing the selection result of the target range is '2' (diagonal designation SLINE line, S to be operated
Inverts the rectangle whose diagonal is the position of the CLMN digit, the position of the ELINE line, and the position of the ECLMN digit (3336, 3340).

In the case of a key input for selecting these target ranges, the processing of the subroutine SET @ END is terminated.

The input keys are keys 112 and 113 related to the movement of the cursor 21,
If it is 114 or 115, cursor movement processing is performed (3337). The end point position is changed by moving the cursor.

In the case of a key input other than the selection of the target range, the key input is performed again.

FIG. 5 shows a subroutine BRUSH for performing a shading process.

First, as shown in FIG. 6C, a window 25 for selecting the type of the hatching pattern is displayed, and the hatching pattern is selected (340).

After the selection of the shading pattern, the shading process is performed according to the variable R す る KIND value for storing the selection result of the target range (34).
1). Shading is performed when R ￥ KIND is '0' (when the character unit is specified), starting from SLINE line, SCLMN digit character to ELINE line, ELINE line.
Shading the character string up to the CLMN digit character with the selected shading pattern. When R @ KIND is "1" (when the line unit is specified), the characters on the lines from the SLINE line to the ELINE line are shaded by the selected shading pattern. When R ￥ KIND is neither '0' nor '1' (when the diagonal is specified), a character in the rectangle whose diagonal is the SLINE line, SCLMN digit position and ELINE line, ECLMN digit position is selected. Shading with a shading pattern.

For example, in the state of FIG. 6A, the 'shaded' key (press the 'underline' key 110 while holding down the '★' key 111)
By pressing, the screen becomes as shown in FIG. 6B, in which the target range is selected and the end point is specified. In this state, when the cursor is moved below the “mouth” and the character unit is specified, the character string from “first” to “mouth” is inverted between black and white, as shown in FIG. A window for selecting the type is displayed. When a shaded pattern, for example, 3 is selected, it is shaded as shown in FIG. 6D.

According to the present embodiment, when the target range is a rectangle, it is not necessary to input a key for designating the rectangle as in the related art, and the number of operation steps is reduced by one.

Hereinafter, another embodiment will be described with reference to the flowchart of FIG.

First, a subroutine SET @ OBJ2 is called to specify an operation target before selecting a function (70).

Next, a subroutine FUNCTION is called to select a function to be executed (71).

The subroutine SET @ OBJ2 for specifying the operation target calls the subroutine SET @ FIRST as shown in FIG. 9, and specifies the starting point (700). Next, the subroutine SET @ LAST is called to specify an end point and select a target range (701).

FIG. 10 is a flowchart of a subroutine FUNCTION for selecting a function to be executed.

In this subroutine, the operation guide 27 is first displayed as shown in FIG. 13C (710), and key input is performed (71).
1).

If the input key is a function key indicating a function, processing of the function corresponding to the key is performed. If the input key is not a function key, the key input is performed again.

For example, the input key is a “shaded” key (press the “underline” key 110 while pressing the “★” key 111)
If so, the subroutine BRUSH shown in FIG. 5 is called and a hatching process is performed (712, 713).

FIG. 11 shows a flowchart of the subroutine SET @ FIRST for designating the starting point.

In this subroutine, key input is performed first (700
0). If the input key is the 'specify' key 116, the cursor line position,
Store the digit positions in the variables SLINE and SCLMN respectively (700
1). To indicate that the starting point has been specified, use SLINE
The character at the line and SCLMN digit position is displayed in black and white reversed (7002), and the processing of the subroutine SET @ FIRST ends.

The input keys are keys 112 and 113 related to the movement of the cursor 21,
If it is 114 or 115, cursor movement processing is performed (7003). The start point is changed by moving the cursor.

In the case of a key input other than the “specify” key 116, the key input is performed again.

Subroutine SET for specifying end point and selecting target range
Fig. 12 shows the $ LAST flow chart.

First, options for selecting a target range are displayed on the matrix 23, and the operation guide 26 is displayed as shown in FIG. 13B (7010), 7011).

 Next, key input is performed (7012).

After the key input, the cursor line position and column position are set to the variables ELINE and ECL, respectively, to make the current cursor position the end point.
It is stored in the MN (7013).

 Next, the input key is determined.

If the input key is the '7' key 107, or the '8' key 108, or the '9' key 109, since it is a character unit designation, store '0' in the variable R ￥ KIND storing the selection result of the target range,
SLINE line to be operated, ELINE from SCLMN characters
Inverts the character string up to ECLMN digits on the line (7014,
7018).

If the input key is the '4' key 104, or the '5' key 105, or the '6' key 106, since it is a line-by-line designation, store '1' in the variable R ￥ KIND which stores the selection result of the target range, The line from the SLINE line to the ELINE line to be operated is inverted between black and white (7015, 7019).

If the input key is the '1' key 101, or the '2' key 102, or the '3' key 103, it is a diagonal designation, so store '2' in the variable R ￥ KIND storing the selection result of the target range, Operation target SLINE line, SCLMN column position and ELINE line, ECLMN
Invert black and white rectangles with diagonal positions (7016, 702
0).

In the case of a key input for selecting these target ranges, the processing of the subroutine SET @ LAST is ended.

The input keys are keys 112 and 113 related to the movement of the cursor 21,
If it is 114 or 115, cursor movement processing is performed (7014). The end point is changed by moving the cursor.

In the case of a key input other than the selection of the target range, the key input is performed again.

For example, when the 'designation' key 116 is pressed in the state of FIG. 13A, the state becomes as shown in FIG. 13B, and a state in which the target range is selected and the end point is designated is set. In this state, if you move the cursor under the "su" of the "is" and specify the diagonal,
As shown in FIG. C, a rectangle having a diagonal of “first” and “su” is inverted in black and white. In this state, press the 'shaded' key ('★'
When the user presses the 'underline' key 110 while pressing the key 111), a window for selecting the type of the hatched pattern is displayed as shown in FIG. 13D. When the hatching pattern is selected, the hatching is performed as shown in FIG. 13E.

The selection of the target range may be performed by displaying a matrix to be selected when the start point is specified.

According to this embodiment, when the target range is a rectangle, it is not necessary to input a key for designating the rectangle as in the related art, and the number of operation steps is reduced.
