Abstract

PURPOSE:To simplify processing so as to facilitate a counter measure to line command change or the like by providing a line command processing routine, a line command determining table and a processing determining table, and interpreting a line command by using the tables. CONSTITUTION:A screen processing routine 3 executes screen edition by using screen data 11 and transfers a line command table 5 to a line command processing routine 7 to request the interpretation of the line command. The routine 7 interpretes the line command of the screen data 11. Namely the routing interpretes the line command of the table 5 and returns the interpreted result to the routine 3 as a subscript table 6. In order to form the table 6, the routine 7 determines processing to be executed correspondingly to the line command by using a line command determining table 8 and a processing determining table 9. The tables 8, 9 determine processing to be executed correspondingly to the line command. The routine 3 executes the line command based upon the interpretation.

Description

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 method, and more particularly to a full-screen editor control processing method in which processing is simplified by using a table.

A full-screen editor, unlike a line editor that repeats line command reading and interpretation screen editing line by line, reads all line commands on the processing screen and then interprets each line command to perform screen editing. Take.

[0003]

2. Description of the Related Art Screen data to be processed by a full screen editor has a structure as shown in FIG. That is, for each line, the line command CMD and the subscript (line number) SE from the beginning
It consists of Q and an article (for example, "Once upon a time"). For example, eleven kinds of illustrated line commands are prepared.
For example, the line command “CC” is an instruction that works as a set with “CC to CC, A” or “CC to CC, B” and copies the portion enclosed by CC to A or B. In the case shown,
Articles on the “002” and “003” lines are copied after the “004” line.

Interpretation and execution of such a line command is shown in FIG.
It is performed according to the flowchart as described above. As is clear from FIG. 8, this process begins with the line command (IDX =
1) Repeatedly refer to from 1) to determine the type by if statement etc., execute the process (that is, the command) according to the type, and then return to the main control (flow on the left side in the figure). Is. For example, when the line command “CC” is recognized, control is passed to the “CC process (routine)” (flow on the right side in the figure) to execute a set of line commands such as “CC to CC, A”. Then control is returned.

By the way, the interpretation and execution of this line command is
This is performed by the 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 contents of the screen processing data of each screen routine,
This is because the number of lines is different and it is necessary to prepare for each screen routine.

[0006]

According to the above-mentioned conventional technique, there is a problem that the processing becomes complicated. For example, in order to know the type of line command, the judgment in the if statement must be repeated many times. Further, the processing must be different depending on whether the line command "CC" is followed by the line command "A" or vice versa, which makes each routine 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 prepare 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 in this way, there is a problem that a long time is required to execute the interpretation.

Further, according to the above-mentioned conventional technique, 1 in FIG.
If the specification (description) of one type of line command is changed or the number of types is increased, in order to perform the processing shown in FIG. 8, it is not possible to deal with it without modifying each processing routine and main control routine. There was a problem.

Furthermore, since each screen processing routine must be provided with a line command interpretation execution routine, there is a problem that the screen processing routine becomes large.
It is an object of the present invention to provide a full screen editor control processing method that simplifies the processing.

It is another object of the present invention to provide a full-screen editor control processing method that can easily cope with changes in line commands. Another object of the present invention is to provide a full-screen editor control processing method having a simple screen processing routine.

FIG. 1 is a block diagram of the principle of the present invention, showing a data processing apparatus according to the present invention. Figure 1
In, the screen processing routine 3 edits the screen using the screen data 11. For this purpose, the screen processing routine 3
Line command table 5 line command processing routine 7
And ask to interpret the line command.

The line command processing routine 7 interprets the line command of the screen data 11. That is, the line command in the line command table 5 is interpreted, and the result is interpreted as the subscript table 6
Is returned to the screen processing routine 3. This subscript table 6
For creation, the row command processing routine 7 uses the tables 8 and 9 to determine the processing to be performed corresponding to the row command. The tables 8 and 9 define the processing to be performed corresponding to the row command.

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

[0013]

According to the present invention, since the line command processing routine 7 interprets the line command, each screen processing routine 3 may be provided with a line command executing section (that is, a data rearranging section 4). Each screen processing routine 3 can be reduced in size. Further, 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 command using the tables 8 and 9, the process is complicated and the interpretation does not require a long time. That is, it is possible to refer to the tables 8 and 9 a few times without repeating the determination in the if sentence a large number of times. Further, since various combinations of line commands and the processes corresponding thereto are taken into consideration in the tables 8 and 9, the line command processing routine 7 is not complicated and lengthened.

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

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

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

The screen data 11 is line by line from the beginning,
It is composed of a line command CMD, a subscript (line number) SEQ, and an article (for example, "Once upon a time"). The types of line commands and the meanings of instructions are the same as those shown in FIG.
Some lines have blank line commands. The subscripts are added in order from the first line and represent the line number of each line. The article is the actual data and the content displayed on the screen. Therefore, the screen obtained on the display device 12 is, for example, the screen data 11-
1, the line command and subscript of each line are omitted.

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 the lines (100 lines) of the screen data 11-1, that is, all the screens (full screens) 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 generation, each screen processing routine 3-1
2 and 3-2, only the data rearranging unit (line command execution routine) 4 is incorporated by the full-screen editor 2, and no line command processing (interpretation) routine is incorporated.

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

The interface between the screen processing routine 3 and the line command processing routine 7 is as shown in FIG. For example, when making a request from the screen processing routine 3-1 to the line command processing routine 7, the line command table 5-
1 and the total number of lines (100 lines). On the other hand, at the time of this response, it is the subscript table 6-1 and the number of processing lines (how many lines have been obtained as a result of the processing). The screen processing routine 3-2 also uses the interface shown in the figure.

FIG. 3 shows the 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 a table in which only the row command CMD portion of the screen data 11-1 is extracted and arranged so as to correspond to each row. At this time, the line for which the line command is blank is left as it is. Therefore, in reality, "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 the interpretation of the line command only by the subscript (line number).

In the illustrated case, in the line command table 5-1, there are "CC to CC" on the second and fourth lines and "A" on the sixth line. The 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 and does not exist in the subscript table 6-1. In addition, “I” on the 9th line of the line command table 5-1
5 "is interpreted as" insert 5 blanks before the 9th line. "Therefore, in the subscript table 6-1," 0, 0, 0 "representing 5 blanks before" 9 "is displayed. , 0, 0 ”is inserted. The line command processing routine 7 performs the above interpretation and creation of the subscript table 6-1. Incidentally, when the tenth line of the line command table 5-1 is processed, the corresponding number of processed lines of the subscript table 6-1 is 17 as shown in the figure.

In the screen processing routine 3-1 which has received the subscript table 6-1, the data rearrangement unit 4 thereof.
(4-1) rearranges the articles according to the subscript table 6-1. That is, in the screen data 11-1, the articles on the first to sixth rows are left unchanged, the articles on the second to fourth rows are inserted again after the articles on the sixth row, and the articles on the eighth row are deleted. Then, insert 5 blank lines before the 9th line. As a result, a new edit 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 process determination table 9 shown in FIG.
The line command determination table 8 is configured to indicate a predetermined position of a process determination table 9 described later for each type of line command. That is, in FIG. 4, the line command determination table 8
Is the process decision table 9 for all the line commands shown in FIG. 7 and “blank” representing an empty line with no line command.
Stores the subscript (number) of. Line command processing routine 7
Is the line command currently being interpreted, eg "CC"
By referring to the line command determination table 8, the subscript “10” is obtained, and the subscript “10” indicates “present” (in the figure, “present” in the process determination table 9;
Refer to the column of "10" in the subscript of (in the figure, which is the vertical direction).

The process decision table 9 defines the process to be performed corresponding to the line command to be interpreted in relation to the line command to be currently interpreted and the line command preceding it. In the figure, the preceding command is expressed as “previous” and is shown in the horizontal direction corresponding to the subscripts. The line command processing routine 7 refers to the line command determination table 8 according to the line command to be interpreted, and refers to the process determination table 9 based on the result, and determines the process to be performed correspondingly. For example, referring to the process determination table 9 by the subscript “10” of the current line command “CC”, if the previous line command is the subscript “15” (that is, “blank”), the “CC” is “previous CC”. ", And the previous line command is the subscript" 3 "(that is," previous CC "), the relevant" C "
It is known that "C" is "after CC", which determines the copy process and the first line or the last line.

When the line command is changed, the line command decision table 8 and the process decision table 9 may be changed. For example, when the number of line commands is increased, the line command is added to the line command determination table 8 so that unique subscripts are associated. Then, in the processing decision table 9, a description (for example, "previous CC") for processing is described in a portion in combination with other possible (permitted to use) line commands. As a result, the correction can be handled without changing the line command processing routine 7.

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

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

Next, the line command processing routine 7 sets the obtained subscript in NOW-IDX (now index register), refers to the processing determination table 9 using NOW-IDX and BEF-IDX, and determines the processing. (Process), and the process is performed (Process). The results of this interpretation are collectively executed later by the screen processing routine 3-1. After this, the line command processing routine 7 executes the IDX
Is incremented by 1, the required value is set in BEF-IDX (processing), and the processing and the following steps are repeated.

Now, the line command table 5-shown in FIG.
If the process 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, BEF-IDX is not updated.

Regarding the second line of the line command table 5-1, NOW-IDX is "10" and BEF-IDX is "1".
5 ". As a result, 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 line, NOW-IDX is "10" and BE is selected.
F-IDX is “3”, “after CC” is selected, and BEF-
IDX is set to "9". In addition, regarding the 6th 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 8th and 9th lines, BEF
-"D" and "I" are selected regardless of the value of IDX. When the above selected process is executed (processed), "C
C-CC, A ", subscripts" 1, 2, 3, 4, 5,
“2,3,4” is added after “6”, 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 decision table, and a process decision table in the full-screen editor control process, the line command can be interpreted by a simple process using the table, and the interpretation time can be shortened. Further, it is possible to easily deal with the change of 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 made small.
