Description

[Detailed Description of the Invention] [Summary] Regarding a processing method in a computer for restoring an original control statement as a source from a control table, an arbitrary control statement that can be specified by a definition of a predetermined format and a control statement generated from the control statement is provided. With respect to control tables, for the purpose of a general-purpose control statement restoration processing method that restores the original control statement from the control table according to the definition, a control table in a predetermined format with the contents specified by the control statement is created using the control statement as the source. In the generating computer, refer to the control table format definition data that defines the configuration of the control table, the control statement format definition data that defines the configuration of the control statement, the control table format definition data, and the control statement format definition data. and means for generating the control statement that is the source of the control table from the control table.

[Industrial application field]

The present invention relates to a control statement restoration processing method for restoring an original control statement that is a source from a control table in a computer.

[Problems to be solved by the prior art and the invention] In computers, so-called system generation (hereinafter abbreviated as SG) is used to set various control tables necessary to configure the system used by the user. It is well known to do this.

In SG, in order to create various control tables etc. for computer control system programs etc. in SG files, as shown in Figure 5, SG control statements in a predetermined format are used to specify the contents of control tables etc. 1 is input to the SG file creation program 3 executed by the processing device 2 using a card input device or the like, and the program generates an SG file 4 consisting of the required control table etc. specified in the SG control statement 1. Additionally, the SG control statement list 5 is output as management data.

The control table generated in the SG file 4 is, for example, a table in the format shown in FIG.

The figure shows an example of a file management table called IFMT, and for example, the first 80 bytes are the SG area set by the SG file creation program 3.

As shown in the figure, this SG area has fields such as an 8-byte logical file name, a 4-byte accommodation volume number, and a 2-byte file status in order from the beginning. Identified by a name as indicated by the alphanumeric string within each column. 308116
The statement is usually configured to input the setting value of the control table by describing the parameter name and its contents corresponding to each field in a predetermined format.

For example, in the case of the above-mentioned file management table, such a control table needs to be created for the number of files that need to be created in the SG, and a large number of SG control statements are generally input to specify them. Therefore, the contents are output as the 5GIII sentence list 5 as described above, and are used as management data necessary for subsequent corrections/additions, expansion of the same type of system, etc.

When the contents set in the SG file 4 are changed, the system operator etc. refers to the SG control statement list 5 and inputs the SG control statement for change in a predetermined format into the SG file creation program. , updates the SG file 4.

If you update SG file 5 in this way,
A complete SG control statement list corresponding to the updated contents cannot be obtained, and if necessary, the SG control statement source card must be replaced and the SG file re-created, making it difficult to maintain management materials. There were problems such as the need for

The present invention aims to provide a general-purpose control statement restoration processing method for restoring the original control statement from the control table according to the definition of an arbitrary control statement that can be defined by a definition in a predetermined format and a control table generated from the control statement. do.

[Means for solving problems]

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

The figure shows the configuration of the control statement restoration processing method, and 11 is a control statement restoration program executed by the processing device 10, which refers to the control table format definition data 12 and the control statement format definition data 13, and Restore and generate the source control statement from the control table, and create the SG control statement list 14 or SG
It is output as a control statement source card 15 or the like.

[For production]

The control table format definition data 12 consists of the field name of each field of the control table, and information indicating the structure of the field in terms of data type and data length.

The control statement format definition data 13 includes information to be specified in each field of the control table, including the parameter name in the control statement, the data type and length of the data, and the specification of the data format when setting it in the control table.

The control statement restoration program 11 sequentially extracts data whose configuration is determined by the control table format definition data 12 for the control table of the SG file 4, and extracts the data whose configuration is determined by the control table format definition data 12.
By referring to the definition of the corresponding data, the source information is restored, combined with the parameter name defined in the information, edited into a predetermined expression format of the control statement, and output.

With this processing method, for any control statement and control table defined by format definition data, it is possible to restore and generate the source control statement from the control table.

〔Example〕

The control table format definition data 12 is definition data constructed based on specification information including information indicating the structure of each field of the control table by data type and data length, as shown in FIG. 2, for example.

In FIG. 2, ¥TBDHF indicates the start of definition data for one control table, and the following parameters in parentheses define the name of the control table, etc.

The next \ENTRY is the start of information that defines the structure of the control table, and indicates that the control table is constructed by arranging the fields defined by \FLD in the following lines in the order in which they are arranged.

Field names, data types, data lengths, and other parameters are defined in the parameters of each definition information starting with \FLD. For example, in the first YFLD statement, the field name is LFN, and the data contains up to 8 bytes of character data (CIIAR). In the next \FL statement, the field name is VMTN, and the data is binary data (IIIN).
This is an example in which a configuration is defined in which up to 2 bits can be entered, and the example shown in FIG. 2 corresponds to the example of the file management table in FIG.

The control statement format definition data 13 is based on specification information, such as the data format of information specified as a parameter of a control statement and the data format when setting it in a control table, as shown in FIG. 3, for example. This is the definition data that is configured.

In Figure 3, ¥5TDEF indicates the start of definition data for one type of control statement, and its parameters define the name of the control statement, and the example indicates that it is a definition statement for a file (FILE). There is.

The next \PARA specifies the definition of each parameter of the control statement, and the parameters of the YPARA statement specify the name, data type, data length, etc. of the control statement parameter, and each YPARA statement specifies the name, data type, data length, etc.
\TSET after the ARA statement defines the setting of the control statement parameters defined in the \PARA statement to the control table, and specifies the control table name, field name, etc. of the setting light.

The first example in the figure is the YPARA statement with the control statement parameter LF
N is character data (CHAR) of maximum 8 bytes, indicating variable length (VAR), and defines that the character data should be set in the LFN field of the IFMT control table using the YTSET statement.

Further, in the parameter of the third YPARA statement, NUM indicates that this control statement parameter is numerical data, and the number of digits is a maximum of five decimal digits.

In the fifth YPARA statement, etc., this control statement parameter is a symbol (SYMB), and one of the symbols defined in two or more YSEL statements following this statement should be specified (parameter (denoted as SEL).

In this case, the \CNV following the \TStiT statement can define that the first parameter is converted into a second parameter and set in the control table. In addition, °
1゛B etc. represent binary "1" etc.

The control statement restoration program 11 sequentially extracts and processes data, one field at a time, determined by the control table format definition data 12, from one control table of the SG file 4, for example, starting from the beginning.

For example, as shown in the processing flow in FIG. 4, when the data of one field of the control table is extracted in processing step 20, the field name of that data defined in the control table format definition data 12 is extracted in processing step 21. , search from the parameter setting light field name of the \TSET statement in the control statement format definition data 13.

In processing step 22, Y that forms a pair with the YTSET statement
The definition starting with the PARA statement is checked, and if the data has not been converted, the data is edited as it is as data of a predetermined data type in combination with the parameter name defined in the YPARA statement in processing step 24, For example, 5GitdJ like parameter name = data? It is restored to a predetermined description format of 11 sentences, and outputted as SG control statement list 4 or source card 15 in processing step 25.

If it is determined in processing step 22 that the data has been converted, the same data is searched from the parameters of the YCNV statement in processing step 23, and the pre-conversion data specified as the corresponding parameter is used. Then, the process from step 24 onward is performed in the same manner as described above.

Thereafter, in processing step 26, it is determined based on the control table format definition data 12 that if any unprocessed fields remain,
Returning to processing step 20, the next field defined in the definition data is processed in the same manner as above, and once all the fields defined in the control table format definition data 12 have been processed, the processing for that control table is completed. finish.

By using the processing method described above, it is possible to restore and generate the original control statement that becomes the source from the control table, so when the SG file is changed, etc. At such times, it is possible to obtain an SG control statement list that matches the latest contents of the SG file.

Furthermore, as is clear from the above description, the control statement restoration program of the present invention allows the user to convert control statement format definition data and As long as the control table format definition data is written and defined, it is possible to perform general-purpose processing.

Note that although the above description has focused on control tables set in SG files, it is clear that the present invention is applicable not only to S and G files but also to other control tables generated using control statements as sources. It is.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a computer, the original control statement of a control table set by system generation etc. can be restored from the control table at any time, so maintenance management of control statements is easy. Furthermore, this function can be used universally by describing the format definition data of control statements and control tables, so it has a remarkable industrial effect of being compatible with a variety of systems.
