DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full-screen editor control processing device , and more particularly to a full-screen editor control processing device using a table to simplify processing.

A full screen editor is different from a line editor in which line commands are read and interpreted on a line-by-line basis, and is different from a line editor in which all line commands on a processing screen are read and then each line command is interpreted to edit the screen. Take.

[0003]

2. Description of the Related Art Screen data to be processed by a full screen editor has a configuration as shown in FIG. That is, for each line, a line command CMD, a suffix (line number) SE from the beginning.
Q and an article (for example, “Once upon a time”). As the line commands, for example, 11 types shown are prepared.
For example, line command "CC" is, "CC~CC, A" replication or although not shown example "CC~CC, B" acts as a set in a portion surrounded by CC on A or B It is an instruction to do. In the illustrated case, the “002” line and the “00”
The article on line 3 is copied after line 004.

The interpretation and execution of such a line command are described in FIG.
It is performed according to a flowchart as shown in FIG. As is clear from FIG. 8, this processing starts with the line command (IDX =
By repeatedly referring to the order from 1), determining the type by an if statement or the like, executing a process corresponding to the type (that is, the command), and then returning to the main control (the flow on the left side in the figure). It is. For example, when the line command “CC” is recognized, control is passed to “CC processing (routine)” (the flow on the right side in the figure), and a set of line commands such as “CC to CC, A” is executed. Then control is returned.

By the way, the interpretation and execution of this line command are as follows:
This is performed by a line command interpretation data rearrangement (execution) routine shown in FIG. This line command interpretation execution routine is provided for each screen processing routine as shown in the figure. This is the content of the screen processing data of each screen routine,
This is because it is necessary to prepare for each screen routine because the number of lines is different.

[0006]

According to the above-mentioned prior art, there is a problem that processing becomes complicated. For example, in order to know the type of the line command, it is necessary to repeat the judgment in the if statement many times. In addition, the processing must be separated depending on whether the line command "A" is present after the line command "CC" or vice versa, and each routine becomes complicated (long). Further, there are many line commands such as "CC" and "MM" which are combined with the line command "A", and it is necessary to provide a processing routine that can cope with various cases, so that each routine becomes complicated. On the other hand, since the processing becomes complicated and each routine becomes long, there has been a problem that a long time is required for executing the interpretation.

Further, according to the above-mentioned prior art, FIG.
If the specification (description) of one type of line command is changed or the type of line command is increased, it cannot be handled unless each processing routine and main control routine are modified in order to perform the processing shown in FIG. There was a problem.

Furthermore, since a line command interpretation and execution routine must be provided for each screen processing routine, there is a problem that the screen processing routine becomes large.
The present invention has a
To provide a screen editor control processor
And

[0010]

FIG. 1 is a block diagram showing the principle of the present invention, and shows a data processing apparatus according to the present invention. FIG.
In, the screen processing routine 3 performs screen editing using the screen data 11. Therefore, the screen processing routine 3
Stores the row command table 5 in the row command processing routine 7
To request interpretation of the line command.

The line command processing routine 7 interprets a line command of the screen data 11. That is, the line commands in the line command table 5 are interpreted, and the result is stored in the subscript table 6.
To the screen processing routine 3. This subscript table 6
For creation, the line command processing routine 7 uses the tables 8 and 9 to determine the processing to be performed in response to the line command. The tables 8 and 9 define processing to be performed in response to a line command.

The screen processing routine 3 executes a line command based on the interpretation. That is, the determined processing is executed. For this purpose, the screen data 1
A data rearranging unit 4 for rearranging one article and executing a line command is provided. Then, the data rearranging section 4 rearranges the articles according to the subscript table 6.

[0013]

According to the present invention, since the line command is interpreted by the line command processing routine 7, each screen processing routine 3 only needs to have a line command execution unit (that is, the data rearranging unit 4). Each screen processing routine 3 can be reduced. Also, since one line command processing routine 7 may be provided for a plurality of screen processing routines 3, the processing can be simplified and resources can be saved.

On the other hand, since the line command processing routine 7 interprets the line commands using the tables 8 and 9, the processing is complicated and the interpretation does not require a long time. That is, it is sufficient to refer to the tables 8 and 9 a few times without repeating the judgment in the if sentence many times. Further, since various combinations of line commands and processes corresponding thereto are considered in the tables 8 and 9, the line command processing routine 7 is not complicated and does not become long.

Further, by using the tables 8 and 9, even when the line command is changed, it is not necessary to modify the line command processing routine 7, and only the tables 8 and 9 need to be modified. Can deal with.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG.
Is provided in a processing unit 1 including a central processing unit (CPU) and a main storage unit (MMU), performs processing such as screen editing based on screen data 11 stored in a data buffer 10, and displays the edited screen. It is displayed on the display screen of the device 12. The operator obtains a screen based on the screen data 11 using the full screen editor 2 from a terminal (not shown).

The screen data 11 is, for example, as shown in FIG. 2, and includes the screen data 1 of "XXX processing <update>".
1-1, screen data 11-2 of “△△△ process <update>”
And so on. The screen data 11-1 is configured by collecting 10 screens (100 rows) of data of 10 lines per screen. The screen data 11-2 is composed of eight lines of data for one screen. In the following description, the screen data 11-1 is appropriately referred to.

The screen data 11 includes, for each line,
It is composed of a line command CMD, a subscript (line number) SEQ, and an article (for example, “Once upon a time”). The type of the line command and the meaning of the command are the same as those shown in FIG.
Some lines have blank line commands. Subscripts are added in order from the first line, and represent the line number of each line. The article is actual data and is the content displayed on the screen. Therefore, the screen obtained on the display device 12 is, for example, screen data 11-
1 is equivalent to omitting the line command and subscript of each line.

The screen processing routine 3 is generated by the full screen editor 2. This generation is performed for each of the read screen data 11-1 and 11-2. For example,
When the screen data 11-1 is designated and the enter key is pressed, all lines (100 lines) of the screen data 11-1, that is, all screens (full screen) are read and interpreted. Therefore, as shown in FIG. 2, a plurality of screen processing routines 3-1 and 3-2 are generated and exist, and correspond to the entered screen data 11-1 and 11-2.

At the time of this generation, each screen processing routine 3-1
And 3-2, only the data rearranging unit (line command execution routine) 4 is incorporated by the full screen editor 2, and the line command processing (interpretation) routine is not incorporated.

On the other hand, only one line command processing routine 7 is provided in advance corresponding to a plurality of screen processing routines 3 generated each time the enter operation is performed, and the line command determination table 8 and the processing determination table 9 are provided. Have. The line command processing routine 7 includes a plurality of screen processing routines 3-
In response to requests from 1 and 3-2, the line command is interpreted and the result is returned to the requester.

The interface between the screen processing routine 3 and the line command processing routine 7 is as shown in FIG. For example, when the screen processing routine 3-1 requests the line command processing routine 7, the line command table 5-
1 and the total number of rows (100 rows). On the other hand, in the case of this response, the subscript table 6-1 and the number of processed lines (how many lines have been processed). Similarly, the screen processing routine 3-2 uses an interface as shown in the figure.

FIG. 3 shows details of the interface between the screen processing routine 3-1 and the line command processing routine 7, particularly the line command table 5-1 and the subscript table 6-1. The row command table 5-1 is obtained by taking out only the row command CMD portion of the screen data 11-1 and arranging it so as to correspond to each row. At this time, a line with a blank line command is left blank. Therefore, in practice, "1, 5, 10, 100"
It is not necessary to add subscripts such as to the line command table 5-1 (in the figure, subscripts are added for explanation). on the other hand,
The subscript table 6-1 shows the result of interpretation of a line command using only subscripts (line numbers).

In the illustrated case, in the row command table 5-1, "CC-CC" is in the second and fourth rows, and "A" is in the sixth row. This combination of “CC to CC, A” is interpreted as “copy the second to fourth lines after the sixth line”. Therefore, in the subscript table 6-1, “2, 3, 4” is added after the subscript “1, 2, 3, 4, 5, 6”. Further, “D” on the eighth line of the line command table 5-1 is interpreted as “delete the eighth line”. Therefore, “8” is deleted from the subscript table 6-1 and does not exist. Also, “I” in the ninth line of the line command table 5-1
"5" is interpreted as "insert five blank spaces before the ninth line." Therefore, in the subscript table 6-1, "0, 0, 0" representing the blank space of five lines before "9". , 0,0 "is inserted. The line command processing routine 7 performs the above interpretation and the creation of the subscript table 6-1. When the processing up to the tenth line of the line command table 5-1 has been processed, the corresponding number of processed lines in the subscript table 6-1 is 17 as shown in the figure.

In the screen processing routine 3-1 which receives the subscript table 6-1, the data rearranging section 4
(4-1) sorts articles according to the subscript table 6-1. That is, in the screen data 11-1, the articles on the first to sixth lines are left as they are, the articles on the second to fourth lines are inserted again after the article on the sixth line, and the articles on the eighth line are deleted. Then, five blank lines are inserted before the ninth line. Thereby, a new editing screen is obtained. This screen is displayed on the display screen of the display device 12.

The interpretation of the line command in the line command processing routine 7 is performed with reference to the line command determination table 8 shown in FIG. 4 and the processing determination table 9 shown in FIG.
In the row command determination table 8, subscripts are stored so as to indicate a predetermined position on a processing determination table 9 described later for each type of row command. That is, in FIG. 4, the line command determination table 8 indicates the subscripts (numbers) on the processing determination table 9 for all the line commands shown in FIG. 7 and “blank” representing a blank line without a line command. Store. In the case of a line command to be interpreted at present, for example, “CC” , the line command processing routine 7
The subscript “10” is obtained for the “ C” by referring to the row command determination table 8, and based on the subscript “10”, the “current” (represented as “current” in the figure) of the processing determination table 9. And the vertical direction in the figure).
Refer to the column "0".

The processing decision table 9 defines the processing to be performed in accordance with the line command to be interpreted in relation to the current line command to be interpreted and the line command preceding the current line command. In the figure, the preceding command is expressed as "previous", and is indicated in the horizontal direction corresponding to the subscript. The line command processing routine 7 refers to the line command determination table 8 based on the line command to be interpreted, and refers to the processing determination table 9 based on the result, and determines the processing to be performed correspondingly. For example, the processing determination table 9 is referred to by the subscript “10” of the current line command “CC” .
If "CC" at the position of SEQ "002" in the example of
If the previous line command is “blank” and the subscript “15”
From the coordinates (10, 15),
It can be seen that “CC” is “previous CC”. SEQ "00
In the case of "CC" at position "4", the previous line command
Since it is “previous CC”, the subscript is “3” and the coordinates (1
It is known from the contents of (0, 3) that the "CC" is the "post-CC". As a result, what should be copied and the first or last line thereof are determined.

When the line command is to be changed, the line command determination table 8 and the processing determination table 9 may be changed. For example, when increasing the number of line commands, the line commands are added to the line command determination table 8 to correspond to unique subscripts. Then, in the processing determination table 9, a description for processing (for example, “previous CC”) is made in a part of a combination with another conceivable (permitted to use) line command. Thereby, it is possible to cope with the modification without changing the line command processing routine 7.

FIG. 6 shows a line command processing flow. FIG.
In the row command processing routine 7, as initial processing, IDX (index register) is set to “1” as a subscript in the row command table 5-1 of the current row command (processing), and BEF-IDX (before index register) is set. Is set to "15" (process). The suffix “15” is a suffix of the previous line command of the processing determination table 9 and represents “blank”.

Next, the row command processing routine 7
It is checked whether or not the value of X is equal to or greater than the total number of lines (the value received from the screen processing routine 3-1) (processing). If the value of X is equal to or greater than the total number of lines, the process ends. If it is smaller than the total number of lines, the type of the line command, ie, the corresponding subscript, is obtained by referring to the line command determination table 8 using the line command of the line (process). If the type cannot be determined, that is, if there is no line command or the corresponding subscript, an error is detected (processing), and the processing is terminated.

Next, the line command processing routine 7 sets the obtained subscript in the NOW-IDX (now index register), determines the processing by referring to the processing determination table 9 using NOW-IDX and BEF-IDX. (Process), and then performs the process (process). The result of this interpretation is collectively executed later by the screen processing routine 3-1. Thereafter, the line command processing routine 7 executes IDX processing.
Is incremented by +1 and the necessary value is set in BEF-IDX (processing), and the processing and subsequent steps are repeated.

Now, the line command table 5 shown in FIG.
Assuming that the processing shown in FIG. Regarding the first line of the line command table 5-1
NOW-IDX is “12”, BEF-IDX is “15”
Becomes Therefore, the process “S” is determined from the process determination table 9. When the process “S” is executed, the first line of the corresponding line command table 5-1 is left as it is.
When the process “S” is selected, the BEF-IDX is not updated.

Regarding the second row of the row command table 5-1, NOW-IDX is "10" and BEF-IDX is "1".
5 ", whereby the" previous CC "is selected.
EF-IDX is set to “3” corresponding to “previous CC”.

Similarly, for the third line, NOW-IDX
Is "12", BEF-IDX is "3" and "S" is selected. For the fourth row, NOW-IDX is "10" and BE
As for F-IDX, “3” is selected and “after CC” is selected.
IDX is set to “9”. For the sixth line, NO
W-IDX is “6”, BEF-IDX is “9” and “A-
CA ”is selected, that is, the processing of“ CC to CC, A ”is selected.

For the eighth and ninth lines, the BEF
-"D" and "I" are selected regardless of the value of IDX. When the above selected processing is executed (processed), “C
C to CC, A ", the subscripts" 1, 2, 3, 4, 5,
After "6", "2,3,4" is added, subscript "8" is deleted, and subscript "0,0,0,0,0" is added before subscript "9".
Is inserted.

[0036]

As described above, according to the present invention,
By providing a line command processing routine, a line command determination table, and a processing determination table in the full screen editor control processing, line commands can be interpreted by simple processing using a table, so that the time required for interpretation can be reduced. In addition, it is possible to easily cope with a change in the line command by changing the table. On the other hand, since it is not necessary to provide a means for interpreting the line command for each screen processing routine, the screen processing routine can be reduced in size.
