Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a program editing device for editing a program to be edited having a storage capacity larger than that of a main storage device.

(Technical background and problems to be solved) When an edit program having a non-volatile auxiliary storage device and having a larger storage capacity than the main storage device is edited and corrected, a part of the edit program in the auxiliary storage device (Editing and correction department)
Is transferred to the main storage device and is returned to the auxiliary storage device after editing and correction. Data transfer and return of a part of the edited program between the auxiliary storage device and the main storage device
This is done automatically depending on the capacity of the main memory and the modification point of the program to be edited, and the operator usually has no concern. In other words, the operator cannot know how much of the corrected portion in a plurality of places is returned to the edited program in the auxiliary storage device. This is because all the modified parts are automatically returned to the edited program in the auxiliary storage device when the editing is completed.

In this case, if the power is cut off due to an external factor during editing, in order to know which part of the corrected part has been returned to the edited program in the auxiliary storage device and which part has not been returned. The operator has to check all the edited programs in the auxiliary storage device, which is very inconvenient and complicated.

(Object of the Invention) The present invention has been made under the circumstances as described above, and an object of the present invention is to provide a method even when the power is cut off during the editing of a program to be edited which has a larger storage capacity than the main storage device. By searching for the mark recorded in the program to be edited, it is possible to find out what range of the program being edited is the part that is not saved in the program to be edited, and to re-edit the program in a short time. It is to provide a program editing device that can be performed in.

(Means for Solving Problems) The above object of the present invention has a non-volatile auxiliary storage device, a main storage device, an edit control unit, a display device, and an input device, and the main storage device When editing and modifying a program to be edited having a larger storage capacity, the editing and modifying section of the program to be edited is transferred from the auxiliary storage device to the main memory device and is returned to the auxiliary storage device after editing and modifying. In the program editing device, a mark (start mark) indicating the beginning portion and a mark (end mark) indicating the ending portion of the editing / modifying portion are transferred on the auxiliary storage device when the editing / modifying portion is transferred to the main storage device. A mark writing / erasing device for writing the corresponding portion of the program to be edited and erasing the mark when returning to the auxiliary storage device, and a mark searching device for searching the mark. It is achieved by providing a device.

(Operation of the Invention) By recording in the edited program in the auxiliary storage device a mark indicating which part of the edited program is transferred from the auxiliary storage device to the main storage device, an external factor may be applied during editing. When the power is cut off, the operator can be informed of which part of the edited program in the auxiliary storage device remains in the unsaved state from the position of this mark.

(Embodiment of the Invention) FIG. 1 is a block diagram showing a configuration example of a program editing apparatus of the present invention. At the start of editing, the editing control unit 1 stores a part of a program 3 to be edited from a non-volatile auxiliary storage device 2. (For example, the area 3A) is transferred to the main storage device 4 as indicated by the shaded area 4A. The capacity of the edited program 3 is larger than the storage capacity of the main storage device 4, and the shaded area 3A of the edited program 3
Indicates a portion transferred from the auxiliary storage device 2 to the main storage device 4 for editing and correction. The contents of the part 4A of the program to be edited 3 transferred to the main storage device 4 are displayed on the display device 5 such as a CRT via a display control circuit (not shown). The operator sees the display on the display device 5 to confirm the correction point and inputs the correction data of the program from the input device 6 such as a keyboard and a mouse. At the same time, the edit control unit 1 executes the transfer and the return of the data of the edited program 3 between the auxiliary storage device 2 and the main storage device 4 by the correction point search signal from the input device 6. Then, the mark writing / erasing device 7 automatically confirms which part of the edited program 3 is transferred onto the main storage device 4, and starts to the corresponding part of the edited program 3 on the auxiliary storage device 2. The mark 8 (“<”) and the end mark 9 (“>”) are written and erased. That is, the mark 8 in FIG.
Hatched area 3A indicated by "<" and mark 9 ">"
Shows the edit program portion transferred from the auxiliary storage device 2 to the main storage device 4.

With the above configuration, when the power is cut off due to an external factor while editing the program to be edited 3, the marks 8 and 9 in the program to be edited 3 are searched by the mark search device 10 after the power is turned on again. It is only necessary to confirm the correction in the range indicated by the marks 8 and 9, and it is possible to re-edit the program in a short time even after the power is turned off during the editing of the large capacity program.

The operation of the device of the present invention will be described below with reference to the flow charts shown in FIGS.

When the editing shown in FIG. 2 is started, the correction section 3A of the program to be edited 3 is transferred from the auxiliary storage device 2 to the main storage device 4 (step S1). This program transfer is performed by the edit control unit 1, and the transferred content is displayed on the display device 5. The area of the program to be edited 3 transferred to the main memory 4 is confirmed by the mark writing / erasing device 7, and the mark writing / erasing device 7 marks 8, 9 indicating the range 3A transferred to the main memory 4. Is written in the edited program 3 (step S2). Subsequently, the operator edits and corrects the program to be edited 3 by using the input device 6 while looking at the display contents of the display device 5 (step S3). If this editing correction is OK and editing is completed (step S4). Alternatively, if the edited program 3 other than the range 4A transferred to the main memory 4 is required (step S5), the marks 8 and 9 are erased from the edited program 3, and the process proceeds to step S6 to write the mark. /
Area that has been edited and corrected in the auxiliary storage device 2 by the erasing device 7.
The marks 8 and 9 of 3A are erased. Next, the edit control unit 1 returns the correction completion unit (4A) of the program to be edited 3 from the main storage device 4 to the auxiliary storage device 2 (step S7), and then confirms whether the editing is finished again (step S8), If the editing is not completed, the process returns to step S1 and the same editing correction process is performed again. When the editing is completed in step S8, the editing is completed.

When the power is suddenly turned off by an external factor during the execution of steps S3, S4, and S5 during the above-described editing process, the marks 8 and 9 in the non-volatile auxiliary storage device 2
Is still written in the edited program 3. Then, as shown in the flow of FIG. 3, after the power is turned on again, the mark search device 10 searches for the mark 8 “<” recorded in the program 3 to be edited (step S1.
0), the edited program 3 is edited and corrected until the mark 9 “>” appears (steps S11 and S12), and the re-edited program 3 is completed.

Although “>” and “<” are shown as marks in the above description, any kind of mark can be used.

(Effects of the Invention) As described above, according to the present invention, the marks 8 and 9 indicating which part of the edited program 3 is transferred from the auxiliary storage device 2 to the main storage device 4 are marked in the auxiliary storage device 2 with the marks 8 and 9. Since the data is recorded in the program 3, even if the power is suddenly cut off due to an external factor during the editing of the large-capacity program, the operator can program the part of the program left in the main memory 4 within the range indicated by the marks 8 and 9. Check, edit and correct,
It is possible to reedit the edited program 3 in a short time.
