Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a program modification information creation support device ζ2 that supports the creation of modification information for a link-edited program efficiently and with high reliability. be.

[Prior art]

Conventionally, to perform this type of processing, the correction information creator prepares the correction information as data for the application program, incorporates it into the job control statement, and executes the batch job (b
atch job) was executed by a computer system (2). Therefore, the system configuration for performing this type of processing is a normal computer system and a job control statement that includes modification information. Figure 1 shows the job control This is an explanatory diagram showing an example of a statement. In the diagram, (1) indicates that the modification information application program name is 5PZAP, (2) specifies the library to be crawled, and (3) specifies the output device. In the application program 5PZAP, the part indicated by the symbol 0) in Figure 1 is input as correction information and executed on the computer system, but in Uυ, the name of the program to be corrected is PR.
It is shown that it is O1, and a is the relative address 0124 of the program called PROI (address is 1
Shown in hexadecimal. Since the start address of PROI is fixed, if you give a relative address, you can read the data at that address from the storage device).
815.

One address location stores 1' byte of data, and 1 byte of data constitutes a 2-digit hexadecimal number, so C2, which reads a 4-digit hexadecimal number such as 1815, is a relative address of 0124. Read the 2-byte data of the address and the following relative Abiref address 0125 and this is 181
This means checking whether it is 5 or not. If it is not 1815, processing will be terminated here, but 181
If the value is 5, proceed to the next process. The next process indicated by the @ sign α 純 instructs to write 1825 in hexadecimal to the contents of relative addresses 0124 and 0125. Therefore, when (I3, ul is executed, the relative address 01
The contents of addresses 24 and 0125 are 1815 to 1825.
1 - Modified.

The process below is an example of modification using the modification information storage area, and α4 is relative address 0128, 0129°0.
The contents of 4 bytes of 12A and 012B are 4770,
Instructing to check whether it is B124,
Q51 instructs to write 47FO, C240 to this location i.

When this is executed, reading the contents of relative addresses 0128-012B results in an instruction to unconditionally branch to the modification information storage area.

The relative address 1242 of the code 161 is an address within the correction information storage area, but the process indicated by the code (161) is the relative address 1242, 1243, 1244, 12
It means to confirm that 4 bytes of 45 are unused, and the code (17) is relative address 1246, 124
4 bytes of 7, 1248, 1249 in hexadecimal
770, instructs to perfume with B124. The same goes for the code and the following.

As described above, in conventional devices, when a correction information creator creates a job control statement, he must write the contents of the correction information in machine language, and when using the correction information storage area, he must write the contents of the correction information in machine language. Since it is necessary to manage and allocate the correction information, it takes a lot of time and effort to create correction information, and has the drawbacks of low reliability. This was done in order to eliminate the correction information, and allows correction information to be entered using assembler language, and allows the user to check the grammar of the correction information, perform application tests, etc. between the correction information creator and the computer system. Provides a program correction information creation support device that allows for efficient creation of correction information by enabling automatic management and automatic allocation of correction information storage areas within a program. It is something to do.

The MACRO statement in (32) indicates that the macro referenced by this correction information is macro ABC in the macro library UTS. The 5ETBASE statements (33) and (34) specify what information is to be written to the base register that stores information for creating addresses. In (33), set the address +6 of the symbol PROI in the base register, and in (34) set the address of the symbol PROI in the base register.
It instructs to set the address of the symbol H10 +10.

The SETARgA statements (35) and (36) associate the modification information storage area with the symbol for using it. Here, the symbols PATCH1 and PATCH2 are control words for the modification information storage area, and manage the next available address and the size of the free area within the storage area.

FIG. 4 is a diagram showing the management of modification information storage areas. In the example shown in the figure, PATCHI and PATCI-42+2 have modification information storage areas A (51) and 8 (52), respectively, and (53). ) is the information (pointer) of the start address of the free area in storage area A (51) and storage area A (51).
The remaining size of storage area B (51) is stored, and a pointer to the free area in storage area B (52) and the remaining size of storage area B (52) are stored in the position shown by (54). Therefore, for example, a new (2N
Assuming that a byte of data is stored, program control (- Therefore, N is added to the value of the pointer in (53) and N is subtracted from the remaining size of A, and in this way, C2 is used as the modification information storage area. A (51) and B (52) are automatically managed, and there is no need for the correction information creator (28) to determine the relative address where the correction data should be stored, as shown in FIG. 1 (17) and (18). 〇The sentences starting with / starting from code (37) in Figure 3 are written in assembler language in the format /address/changed content (previous content)/.The previous content is unnecessary if not checked. It is o@.
