Abstract

PURPOSE:To advance correction processing without remaining any error, by fractionizing the condition of processing control over check control statements for an object to be corrected, and providing a step for confirming the completion of normal correction. CONSTITUTION:The 1st comparison part 14 compares data in the address 100 of a load module 11 specified by the position data of a VER statement with the current data of a VER statement 12. A decision making part 15 switches control according to the comparison result. When their coincidence is obtained, a decision on normal processing is made and an advance to a next correction step is made. When not, a searching part 16 is actuated to search for a REP statement 13 having the same position data as the position data of the VER statement 12. In this case, the REP statement 13 for specifying a corresponding address is detected. Then, the 2nd comparison part 17 compares data at a specified position of the load module with the corrected data of the REP statement 13. In this case, coincidence is obtained, so a corrected message is outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a ZAP data modification processing method for a load module in a data processing system, and in particular, to a second method for processing a ZAP data modification process in the middle of the process and restarting the process from the beginning. The present invention relates to a ZAP data correction processing method having a rounding control means to avoid an error response when correcting a file.

Technical background When modifying a load module number, ZAP data is used as a means to enable direct modification without going through a link editor. ZAP data is NAME statement, VE
Consists of R and REP sentences.

The NAME statement specifies the name of the module and its control section to be modified. For example, NAME
A C, Load module name X, 111181 Indicates section master designation. The VER statement is called a check control statement, and is used as a means to prevent erroneous modification by checking the current state of the location to be modified.

For example, VER100FF indicates that the location to be corrected is address 100, and its contents should currently be rFFJ. The worst R
The EP statement is called a modification control statement and serves as data that specifies the content to be rewritten. For example, REP 100 80 changes the contents of address 100 (rFFJ on the upper side) to "80".
1, which indicates that it will be rewritten and corrected.

Inspection control statements and modification control statements are used bare, and are prepared in the same number as the parts to be modified.

FIG. 1 shows the general configuration of a ZAP data processing system. In the figure, 1 is a processing unit, 2 is a memory, 3 is a volume DASD for direct access and stores a load module, and 4 is an input/output processing unit.
Load module X or its control section A specified by the NAME statement is loaded from DASD to memory, and the correction processing results are written back to DASD.

Reference numeral 5 denotes an inspection control unit, which performs a process of checking the current state of the correction portion specified by the VER statement. Reference numeral 6 denotes a correction processing unit, which performs an RE on correction points confirmed by the inspection processing unit 5.
Modify the contents specified in the P statement. 7 indicates NAME statement data, 8 indicates control section A of loaded load module X, 9 indicates VER statement data, and 10 indicates REP statement data.

FIG. 2 is a flowchart showing a conventional control procedure for processing operations in the processing system shown in FIG.

The figure will be explained below.

0 reads all NAME statements, inspection control statements, and modification control statements. In (2), the load module (control section) specified by the NAME statement is read from DASD. In (2), the most robust test control statement is read out (1) and its data is compared with the data at the specified location in the load module. If there is a match, apply the pair of correction control statements to correct the location.

Return the corrected load module to DASD.

In step 2, it is checked whether the modification is finished, and if it is, in step 2, the next check control statement is read out and the process is repeated from @.

In this way, when it is detected that all modifications have been completed, the process ends. Furthermore, if the data in the inspection control statement and the data in the corresponding location of the load module do not match in (2), the error message (2) is output and the correction process is stopped.

When performing correction processing using such ZAP data, the processing may be interrupted for some reason.

At this time, if the correction process is performed again using the same ZAP data, the current data of the inspection control statement and the contents of the correction target part will not match in the part where the redundant correction is to be made, and an error response will occur. Therefore, there was a problem that correction processing was impossible.

OBJECTS AND STRUCTURE OF THE INVENTION The present invention solves the problems of the conventional method described above.
When the same ZAP data is multiplied twice, the processing control conditions of the inspection control statement for the part to be corrected that has already been corrected can be refined to confirm that it has been corrected correctly. By providing this, even if there is a mismatch between the current data in the inspection control statement and the corresponding data in the load module, the correction process can proceed without an error only if it can be determined that the correction method is normal. It is intended to do so.

The present invention has a configuration for this purpose, including a processing device, a memory for storing inspection control statements and modification control statements, and a direct access volume for storing a load module to be modified. In the ZAP data processing system, the correction control statement is composed of position data and correction data, and the data at the position in the load module specified by the position data of the test control statement and the current state data of the test control statement. a #11 comparison means for comparing the above inspection control statement; and when the first comparison means indicates a mismatch, a means for searching for a modified control statement having position data that matches the position data of the inspection control statement; and the search means a second comparing means for comparing the corrected control statement with the data at the position in the load module where a mismatch was previously detected by the first comparing means, when the corrected control statement is found; When the second comparing means indicates a match, it is determined that the data at the position in the load module has been corrected, and control is performed so that the process proceeds to the next correction process without causing an error.

Examples of the invention The present invention will be explained in detail below based on examples.

3A and 3B show a specific example of ZAP data modification processing according to the method of the present invention. FIG. 4 is a flow diagram showing the control procedure of the system of the present invention, shown in comparison with FIG.

FIG. 3A shows the operation in the first interrupted ZAP data modification process. In (1), NAME
Input ZAP data consisting of a sentence, a VER sentence, and a REP sentence. In (11), read into the load module
Compare with FJ and confirm a match. 01 (l, r100
Replace the content rFFJ of address J with the modified data "80" of the paired REP statement.

Now address 100 of the load module becomes the modification method. After this, it is assumed that the correction process is interrupted.

Figure 3B is based on the ZAP data used in Figure 3A.
This shows the operation when redoing the correction process. Press ψ to re-enter the zAP data.

In M, 100 of control section A is again set by the VER statement.
The contents of the address are examined. At this time, since the content of address 100 is modified to "80", it does not match the current data rFFJ of the VER statement. In the conventional method,
At this time, an error message is output, but in the method of the present invention, the RE with the same position data (at Vl)
Correction data of P sentence “80” and content of address 100 “80”
Compare with. Since a match is obtained here, the previous VER
A method for correcting inconsistencies in sentence inspection without treating them as errors,
A correction method message is output, and the next VER statement is inspected.

The above processing is performed in the controller 11i of the 4th diagram.

■,■ are shown together. In addition, in the same figure.

Steps ① to ② are the parts according to the conventional method explained in FIG.

FIG. 5 is a functional configuration diagram of the system of this embodiment.

In the figure, reference numeral 11 indicates a load module control section, 12 indicates a VER statement, 13 indicates a REP statement, 14 indicates an @1 comparison section, 15 indicates a discrimination section, 16 indicates a search section, and 17 indicates a second comparison section.

In operation, the first comparison unit 14#'i first compares the data "80" at address 100 of the load module ll specified by the position data of the VER statement and the current data rF of the VER statement 12.
Compare with FJ. The determining unit 15 switches control according to the comparison result. - If the error occurs, the process is normal) and proceed to the next correction step. If there is no match, the search unit 16 is activated. The search unit 16 searches for a REP statement 13 having the same position data as the position data of the VER 112. in this case,
REP statement 13 specifying the corresponding address 100 is detected. Next, the second comparing section 17 is activated. The second comparison unit 17 compares the data “8” at the specified position of the load module 11.
o'' and the corrected data rsoJ of the REP text. In this case, since a match is obtained, a corrected message is output and the process proceeds to the next correction processing step.

If the search unit 16 fails to search for a REP statement with data at the same location, or if the second comparison unit detects a mismatch between the data in the load module and the modified data in the REP statement, see Figure 11!5. Although omitted in Figure 4, it is determined that an error has occurred and an error message is output as shown in the route from ■ and from 0 to ■ in FIG.

Effects of the Invention As described above, according to the present invention, even if some kind of failure occurs during the correction process and the process ends abnormally, there is no need to check the interruption point and change the correction value. By directly multiplying the entire previous modified data twice, the modification process can be restarted from the beginning, and the efficiency of the modification process can be greatly improved.
