Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as a computer having a line number and capable of inputting and executing a program for processing in the order of the line number.

[0002]

2. Description of the Related Art FIG. 8 is a schematic view of a main part of a conventional device.

Reference numeral 81 denotes a CPU (Central Processing Unit), which performs processing such as reading keys, displaying, and writing programs in the RAM 84. Reference numeral 82 denotes a display unit for displaying characters, numbers, etc. on the LCD. Reference numeral 83 denotes a ROM, which stores information such as a procedure by which the CPU performs processing.

Reference numeral 84 is a RAM, which is a program and a CPU.
Information necessary for processing by 81 is stored.

Reference numeral 85 is an input unit for inputting characters and numbers in KEY. In a conventional device, as a method of copying a program having a line number, the line to be copied is edited and the line number is changed and input is performed. Also, the move was performed by deleting the original line after copying.

When copying or moving a plurality of lines, it is necessary to repeat the above operation for the number of lines.

Furthermore, if there is no space in the line numbers at the copy and move destinations, it is necessary to execute a command for renumbering line numbers (RENUM command in the case of BASIC language) to make a sufficient space for line numbers. .

[0008]

As described above, according to the conventional method, when copying a plurality of lines, it is necessary to edit each line and change the line number before inputting. In the move, the copy must be performed and then the deletion must be performed. These operations are very cumbersome and time-consuming.

Further, it is necessary that the line numbers of the copy and move destinations have a space, and if there is no line number, the line numbers must be re-assigned to make a space number. For example, if five lines are to be copied and moved between the lines of line numbers 10 and 11, the lines after line number 11 must be replaced with the line numbers after 16 and then copied and moved. If you mistakenly copy or move without creating a blank number, the original line will be deleted and rewritten to the copied or moved line.

Furthermore, GOTO, GOSUB (BASIC
In the case of a program that uses an instruction that changes the order of processing (such as in the case of a language) and the processing is being transferred to the copy source or transfer source, the line number at that location must also be changed (if not changed, There will be no place to move), and you have to do the very tedious work of finding and changing the instructions.

Also, a command (BAS) for changing line numbers
In the IC language, in the RENUM command), in order to copy and move when replacing, it was necessary to think and execute "from what number the line after the other should be changed".

[0012]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems, and has a line number, and an electronic device capable of inputting and executing a program for processing in the order of the line number When copying or moving in line units of, the line number automatic adding means that automatically assigns the line number at the copy / moving destination to each line to be copied / moved, and the line number in the program that changes the line number by copying / moving An electronic device having a line number automatic changing means for automatically changing a line number for each line.

[0013]

With the above-described structure, in the present invention, the line numbers are automatically re-assigned, so there is no need to edit each line and re-assign the line numbers. Can be copied and moved on time.

If there is no space in the line number, copy,
It creates an empty area that can be moved, so you can avoid rewriting the program by mistake.

Further, if there is an instruction for shifting the processing order to the copy source or the move source, the line number at that location is automatically changed, so that it is not necessary to perform troublesome work.

R] key.

FIG. 3 is an explanatory diagram of an embodiment of the present invention. Here is an example of copying a program. In this example, two lines of line numbers 10 and 11 are copied between line numbers 11 and 12. When the COPY key is pressed, the state of (a) is entered and the copy source area can be designated. In this state, the first line and the last line of the copy source are designated by the cursor key and the [ENTER] key. In the example, first, the cursor is moved to the line with the line number 10 and the [ENTER] key is pressed, and then the cursor is moved to the line with the line number 11 and the [ENTER] key is pressed (b). When the copy source is specified, the next copy destination can be specified. In this state, press the cursor keys and [ENT
Specify the copy destination with the [ER] key. In the example, line numbers 11 and 1
Since copying will be done between 2 and so, move the cursor to the line of line number 12 and press the [ENTER] key (c). (D) is a state after the copying is executed. It can be seen that the line number 12 before copying is changed to the line number 14 and the lines 12 and 13 are copied. Also, "GOTO" that was in line number 11 before copying
The command "10" is copied to line number 13 and "GOTO 1
You can see that it has changed to 2 ".

Next, FIG. 4 will be described. Similar to FIG. 3, FIG. 4 is also an explanatory diagram of an embodiment of the present invention, and here, an example of moving a program is shown below.

In this example, the two lines of line numbers 10 and 11 are moved to before line number 13. When the MOVE key is pressed, the state shown in (e) is entered, and the source area can be designated. In this state, the cursor key and the [ENTER] key are used to specify the start line and the end line of the movement source. In the example, first move the cursor to the line number 10 and press the [ENTER] key, then use the cursor key to move the cursor to the line number 11 and press [E].
Press the [NTER] key (f). After the move source is specified, the move destination can be specified next. In this state, the cursor key and [ENTER] key are used to specify the destination. In the example, the cursor moves to the line number 13, so the cursor is moved to the line number 13 and the [ENTER] key is pressed (g).
(H) is a state after the movement is executed. It can be seen that the line number 13 before the movement is changed to the line number 15 and the lines are moved to the line numbers 13 and 14. In addition, the command of "GOTO 10" in the line numbers 11 and 13 before the movement is "GOTO
You can see that it has changed to 13 ".

The above is the description of the embodiments of the present invention.

Next, a flow chart showing the operation of the present invention will be described with reference to FIGS. 5, 6 and 7, respectively.

FIG. 5 is a flowchart of the copying process after the COPY key is pressed.

In S50, the first line of the copy source is designated by the cursor key and the [ENTER] key, and the line number is RA.
Store in the area START on M.

In S51, the last line of the copy source is designated by the cursor key and the [ENTER] key, and the line number is RA.
Store in the area LAST on M. START to LAS
The T line is highlighted.

In step S52, the copy source is the cursor key and [E
[NTER] key, specify the line number in the area TO_LINE_NEXT on the RAM, and the previous line number T
Store in O_LINE.

In S53, in order to obtain the number of lines of the copy source,
Calculate LAST-START + 1 and store in LENGTH.

In step S54, TO_L is calculated in order to determine how many line numbers are available in the copy source specified in step S52.
INE_NEXT_TO_LINE-1 is calculated and RA
Store in area AKI on M.

In S55, the number of lines of the copy source (LENGTH) obtained in S53 and the empty line number obtained in S54 (AK
I) is compared, and if LENGTH <= AKI,
When it is determined that copying is possible, the process proceeds to S57.

If LENGTH> AKI, copying cannot be performed, so the process of S56 is performed to create a sufficiently empty line number.

In step S56, the line numbers are reassigned to create an empty line number for LENGTH. Specifically, TO_
The line numbers of all lines after LINE_NEXT are set to LEN.
Add GTH-AKI. Also, GOSUB, GOTO
When the jump destination such as "TO" is a line number after TO_LINE_NEXT, it is similarly added to the line number.
(Same processing as BASIC language RENUM)
If ART and LAST have a line number larger than TO_LINE_NEXT, START and LAST are also corrected.

Finally, TO_LINE and TO_LINE_
Perform NEXT correction.

In S57, the copy source is copied to the copy destination. At that time, the line numbers are sequentially incremented from TO_LINE + 1 by 1
Copy while changing the intervals.

In S58, the copied area (TO_L
GOT flying from INE + 1 to TO_LINE_NEXT-1) to the copy source (between START and LAST)
When checking whether there is an instruction such as O or GOSUB, the jump destination is changed to within the copied area. Specifically, the line number of the jump destination is calculated from START, and the value is replaced with the line number added to TO_LINE + 1.

FIG. 6 is a flowchart of the moving process after the MOVE key is pressed. S60 to S66 are shown in FIG. 5S.
It is the same except that the copy source and the copy destination in 50 to S56 are changed to the move source and the move destination.

In S67, a copy is made as in S57 of FIG.

At S68, the source (S
GOTO, GOS flying from TART to LAST)
If there is an instruction such as UB, the jump destination is changed to the destination area. Specifically, the line number of the jump destination is calculated from START, and the value is calculated as TO_
Change to the line number added to LINE + 1.

At S69, the source (from START to LA
The area indicated by ST) is deleted. Figure 7 is a copy (movement)
6 is a flowchart of a routine for performing a process of designating a first line, a last line, and a line to be copied (moved).

In step S70, the line number of the first line of the program is stored in the area LINE on the RAM. (Initialization) S71 is waiting for a key, and waits until a key is pressed.
When the key is pressed, the process proceeds to S72.

In S72, it is determined whether or not the pressed key is the up cursor key, and if it is the up cursor key, S7
Go to step 6. If not, the process proceeds to S73.

In S73, it is determined whether the key is the down cursor key, and if so, the process proceeds to S77, and if not, the process proceeds to S74.

In S74, it is determined whether the ENTER key is pressed, and if so, the process proceeds to S75. If different,
It moves to S71 and waits until the key is pressed.

Step S75 is a process when the ENTER key is pressed. If the line number stored in the LINE at that time is designated, the line number is returned and the process ends.

S76 is processing of the up cursor key,
The line number immediately before the line number stored in LINE is obtained, the line number is stored again in LINE, and the process proceeds to S78.

At step S77, the down cursor key is processed.
Find the line number next to the line number stored in LINE
The data is stored again in INE, and the process proceeds to S78.

In S78, the screen and cursor are displayed, and S
Return to 71 and wait for the key to be pressed. In the line designation process, the processes of S71 to S78 are repeated until the ENTER key is pressed.

As can be seen from the above explanation, both copying and moving,
Multiple lines can be copied (moved) to an arbitrary position by a single simple operation of designating a copy source (moving source) and a copy destination (moving destination).

Further, before copying (moving), it is checked whether or not there is a sufficient space in the line number, and if there is no space, an empty line number is automatically created, so there is no need to erroneously rewrite the program.

Furthermore, since the line numbers are automatically changed,
There is no need to perform the troublesome operation of changing the line numbers after copying (moving).

Others The present invention is not limited to the embodiments described above and shown in the drawings, and it is needless to say that the present invention can be appropriately modified and implemented without departing from the scope of the invention.

[0053]

According to the present invention, since the line numbers are automatically re-assigned, it is not necessary to edit each line and re-assign the line numbers. Therefore, a plurality of lines can be easily operated by one operation. You can copy and move in a short time.

If there is no space in the line number, copy,
It creates an empty area that can be moved, so you can avoid rewriting the program by mistake. Furthermore, if there is an instruction that shifts the processing order to the copy source or the move source, the line number at that location is also changed automatically, so there is no need for troublesome work.
