〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The editor control mechanism is under the operating system environment, and FIG. 1 shows, as an example, a case where there are two jobs that perform correction processing. The state management unit 1 is activated by an activation request primitive a that includes a target name to be modified or newly created. The status management unit 1 currently stores the number of jobs that are currently modifying the same object at the same time, and when a new job is activated, adds 1 to the number of jobs currently being stored. After adding 1 to the number of jobs in the state management unit 1, a startup request primitive b is sent to the modification target storage unit 2 that stores the target to be modified. If this does not exist, a new one will be created.

After receiving the activation request primitive b, the correction target storage unit 2
checks the creation status of the modification target storage unit 3 which stores the same content as the modification target, and if the modification target storage unit 3 has not been created, creation is performed by the creation request primitive C. After creating the correction target storage unit 3, the correction target storage unit 2 uses the creation request primitive d to create an operation correction target storage unit 4 having the same content. After creation, the modification target storage unit 2 activates the modification unit 5 using the activation request primitive e.

The correction unit 5 that has been activated stores the following information in the operation correction target storage unit 4.
Modification unit 5 accessed and modified using internal command f1
response primitive f2 indicating that the modification work has been completed.
When the operation correction target storage section 4 receives the operation correction object storage section 4, the operation correction object storage section 4 activates the object content comparison section 6 in response to the response limit g, and transfers the modified contents of the storage object. When the target content comparison unit 6 is activated, it transfers a request primitive h requesting the modification target storage unit 2 and the modification target amount storage unit 3 to transfer the content of the storage target that has not undergone the modification process. The correction target storage unit 2 and the correction target amount storage unit 3, which have received the request primitive h from the target content comparison unit 6, send a setting request signal 111 and a signal i21 indicating that they are in use to the correction target usage state management unit 7, respectively. send. Modification target state management unit 7 that receives the setting request signal 111 and signal i21
is a response signal 112. indicating availability. signal 122,
The data are transferred to the modification target storage section 2 and the modification storage section 3, respectively. If the response signal i12 has content indicating that it can be used, regardless of the content of the response signal i22, the modification target storage unit 2 will store the content of the stored target that has not undergone modification processing via the transfer primitive j1. is transferred to the target content comparison unit 6. If only the response signal i22 has content indicating that it can be used, the correction target amount storage unit 3 transfers the transfer primitive j
2, the content of the target that has not undergone the correction process is transferred to the target content comparison unit 6. Response primitive 112.
If both of i22 have contents indicating that they are unusable, the correction target storage section 2 creates a new correction target amount storage section having the same storage contents.

The same content as the object stored in the modification target storage unit 2 is received by the transfer primitive j1 or j2, and after being modified by the modification unit 5, it is stored in the operation modification target storage unit 4. The target content comparing unit 6, which receives the content of the target in the response primitive g, compares the two and makes it correspond to the line number added to the content before modification of the target received in the transfer primitive Jl or j2, After extracting the correction portion, the list element is output to the operation target correction section list storage section 8 using the response primitive 1. After outputting response primitive 1 to operation target modification unit list storage unit 8, target content comparison unit 6 outputs response primitive k to state management unit 1.

An operational correction object storage section 4' and an object content comparison section 6', which are generated in order to simultaneously and separately correct objects in memory.
and creation request primitive d', internal command 1', response primitive f2', response primitive g', and request primitive h'.

The transfer primitive j1', the transfer primitive j2', the response primitive 1', and the response primitive 1' are the operation modification target storage unit 4. Target content comparison unit 6, creation request primitive d, internal command fl, response primitive f2. Response primitive g, request primitive h, transfer primitive j1. Transfer primitive j2. Response primitive 1. Each response primitive has exactly the same content.

Upon receiving the response primitive k, the state management unit 1 examines jobs that are currently modifying the same target at the same time.

As a result of the investigation in the state management unit 1, if the number of jobs is 2 or more, the state management unit 1 decrements the number of jobs by 1 and then outputs a response primitive S to the operating system.

As a result of checking with status management unit 1, if the number of jobs is 1,
The state management unit l sends an activation request primitive m1 to the merge execution unit 9. Thereafter, the state management unit 1 sends an activation request primitive m2 to the correction target storage unit 2, and sends an activation request primitive m3 to the operation target modification unit list storage unit 8.

The merge execution unit 9 that received the startup request primitive m1 performs the following steps:
The transfer primitive n1 receives the content before modification of the stored target from the modification target storage unit 2, and from the operation target modification unit list storage unit 8, the content is made to correspond to the line number added before the modification of the stored target. , after receiving the currently stored modified part and its contents in the transfer primitive n2, integrate the two,
The result is transferred to the corrected target storage unit 10 using a response transfer primitive n3. After transferring the response transfer primitive n3, the merge execution unit 9 sends the activation request primitive 0 to the memory erasing unit 11.

The memory erasing unit 11 that has received the activation request primitive 0 sends the erasure request primitive p1 to the modified target storage unit 10, erases the erase request primitive p2 of each of the plurality of target content comparison units 6 and 6', and sends the erase request primitive p1 to the modified target storage unit 10, and erases the erase request primitive p2 of each of the plurality of target content comparison units 6, 6', and sends a plurality of corrections for operation The deletion request primitive p3 is sent to each of the target storage units 4 and 4', and the deletion request primitive p4 is sent to the operation target modification unit list storage unit.

Modified target storage unit 1 that received modification request primitive p1
0 is deleted after the corrections received in each job are combined and the newly corrected contents are transferred to the correction target storage unit 2 using the transfer primitive q.

Also, for the remaining three parties, the erasure request primitive p2
．． p3. It is deleted after receiving p4. Erase request primitive pi, p2. p3. After transferring all of p4, the storage content erasing unit 11 transfers the completion notification primitive r to the state management unit 1. The state management unit 1 that receives the end notification primitive r outputs a response primitive S to the operating system.
