Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a table registration method, and particularly to creating a registration table for managing the citation of an editing exit routine that edits data of communication messages during transmission and return between a terminal and a host computer in a terminal control device. Regarding the method.

When a terminal control device relays communication messages between multiple terminals and a host computer, the formats and processing contents of the communication messages vary depending on the type of terminal and application work, and even for the same message, the terminal The input/output format and the processing format on the host computer are different.

The terminal control device edits the input format of the sent message received from the terminal into the processing format of the host computer, prepares for transmission to the host computer, and then edits the processing format of the reply message received from the host computer. After editing the output format for each device, prepare and send a reply to the terminal device.

Differences in the processing content for sending messages received by the terminal control device and preparing a reply can be handled by preparing processing units (hereinafter referred to as package programs) that operate on the terminal control device for each processing content. For editing work that adjusts the difference between the input/output format of each machine and the processing format of the host computer, an editing section (hereinafter referred to as an editing exit routine) is prepared for each terminal machine and each application task, and the editing exit routine is executed in the above-mentioned package. This is handled by the program calling it. The editing exit routine is designed to operate while referring to an editing parameter section (hereinafter referred to as parameter block) that describes the hardware characteristics of the terminal and message configuration information. Therefore, when a package program requests an edit exit routine to edit a message, it must specify the edit exit routine type (edit exit routine name or edit exit routine entry address) and parameter block type (parameter block name or parameter block entry address). Must be specified in combination.

A package program is a program that runs under the operating system (hereinafter simply referred to as OS) provided in the terminal control device.
Construction is performed by system generation. Conventionally, the above-mentioned edit exit routine and parameter block were also components of the OS, and the above-mentioned OS
selected and edited the necessary OS from the original OS provided by the computer manufacturer, taking into consideration the equipment configuration of the computer system to be installed and the application business.
The OS must be rebuilt by system generation each time there is a change in equipment, expansion, or system configuration. The preparatory work and procedures from system generation to computer operation will be explained below using diagrams.

FIG. 4 is a schematic diagram of the structure of programs and data, both of which are layout diagrams within the main storage medium 300 shown in FIG. In the figure, the package program 20a has n calling parts 201 of the editing exit routine 210, that is, addresses αt (t=1 to n).
in position. However, the calling procedure of the edit exit routine 210 depends on a flag section 231 in a predetermined registration block 230 of the registration table 21a, which will be described later. The registration table 21a has n registration blocks 230, each with an address βt (t=
1 to n). Each registration block 230 is associated with n calling units 201 in the package program 20a in a one-to-one positional correspondence, for example, in the package program 20a.
Calling unit 2 at address α ₃ position (not shown) of a
01 refers to the registration block 230 at the address _β3 location (not shown). This calling procedure is carried out in the judgment block of the flowchart displayed on the right side of the calling section 201 indicated by diagonal lines in the package program 20a.

The edit exit routine data set 22a is a collection of n' edit exit routines 210, and each edit exit routine 210 has an identification name (edit exit routine name) and is located at addresses γ ₁ to γ n'.
The parameter block table 23a is a collection of n'' parameter blocks 220, each of which has an identification name (parameter block name) and is arranged at addresses δ ₁ to δn″.

This is the second stage initialization work to rewrite to the registration table 21a, and write the edit exit routine entry address 233 and parameter block entry address 235 in the registration block 230 that were not filled in in the work of block 1. It's work. That is, the flag section 231 located at address βt is checked, and if the flag is "ON", the edit exit routine data set 22a is searched using the edit exit routine name written in the edit exit routine name entry section 232 as a key, and the same edit exit is searched. When the routine name is found, the entry address γi of the editing exit routine is entered in the editing exit routine entry address entry section 2 of the registration block 230.
33, and then searches the parameter block table 23a using the parameter block name written in the parameter block name entry field 234 as a key, and if the same parameter block name is found, the parameter block entry address δ _j is registered in the register block 230. It is written in the parameter block entry entry address entry field 235. The above procedure is performed for α _t (t=1 to n) of the package program 20a, and at the same time β _t (t=1 to n) of the registration table 21a is
The results obtained by performing step n) are the package program 20b and registration table 21b which are output from block 3 shown in FIG.

The flowchart in FIG. 5 is an execution procedure diagram of the shaded portion (edit exit routine calling section 201) of the package program 20b. In other words,
The address β _t of the registration table 21b is determined in the judgment block.

Checks whether the flag is "ON" or "OFF", and if the flag is "ON", the process branches to the edit exit routine 210 at address γi (see Figure 4), and the edit exit routine 210 goes to address _δj (see Figure 4). The message is edited while referring to the parameter block 220 in (Reference).

As explained above, package program 20
Edit exit routine 2 at address α _t of b (Figure 5)
10 is based on ON or OFF of the flag section 231 of the registration block 230 in the registration table 21b. Therefore, if a terminal is added, changed, or removed, it is necessary to rewrite the flag section 231 (FIG. 5), and if there is a change, it is necessary to rewrite the parameter block. However, writing in the flag section 231 and parameter block name entry section 234 of the registration block 230 is performed by system generation (block 1 in Fig. 2), so there is the inconvenience of having to perform system generation again. . Furthermore, system generation cannot be executed unless the hardware system configuration scale is above a certain level, and system generation is normally performed using a host computer. During system generation work, it cannot be run concurrently with other work, so if it is done during the day, it is necessary to stop the daily work, so it is usually done late at night after the day's work processing is completed. The overload of man-hours during this period becomes a problem.

SUMMARY OF THE INVENTION An object of the present invention has been made in view of the above-mentioned problems, and provides an editing exit routine for editing the format of communication messages from a terminal, and the work of changing, adding, or deleting parameters cited by the editing exit routine. The table registration method of the present invention is to separate from the system generation work and perform it independently. A processing unit with request units in multiple locations,
Editing consisting of an editing section group consisting of a plurality of editing sections that edit the data, and a plurality of editing parameter sections having a predetermined number of editing parameters necessary for editing, which are assigned in one-to-one correspondence when the editing section operates. A registration table consisting of a parameter table and a registration section that is provided corresponding to each of the editing request sections of the processing section and that registers instruction information of the editing section and the editing parameter section that is referenced for each request. In preparation, a flag is set in advance in the registration section based on whether the data editing is necessary or not, and the editing department instruction information and editing parameter section instruction information written in the registration section in which the flag is set are In a system that performs data editing requested based on data editing, a generation means for generating the editing parameter table and a plurality of flags set depending on whether or not the data editing is necessary, and an initialization means for preparing the operation of the processing section. and the editing parameter table and the plurality of flags are generated by the generation means, and the initialization means sets whether editing is necessary or unnecessary based on the generated flags at each position of the registration section. The present invention is characterized in that the editing section instruction information and the editing parameter section instruction information based on the generated editing parameter table are registered, and will be described in detail below with reference to the drawings.

6 and 7 show an embodiment of the present invention, in which FIG. 6 is a processing block diagram showing the flow of preparatory work from system generation to actual operation, and FIG. 7 is a table configuration diagram. It is.

The difference between FIG. 6 and FIG. 2 is that in the system generation work of block 1', the output of the parameter block table 23 is transferred to the generation means of block 4, and the output of the parameter block table 23 is transferred without going through the work of block 2'. The initialization means of block 3' sets the parameter block.
The purpose is to arrange the table 23 in the main storage medium 300. In the figure, block 1' is a parameter block.
Instead of outputting the table 23, the instruction information 24 of the parameter block table 23 generated on the mass storage medium 200' is outputted and notified to the block 4 generating means. This instruction information includes "media type, file position within the medium, number of required parameter blocks and their names, number of calls to the edit exit routine (same as the number of registered blocks)"
etc. are included.

The block 4 receives the above-mentioned instruction information 24 and the combination data 13 of the definition information of the parameter block and the registered definition information of the edit exit routine (the above-mentioned flag), and executes the parameter block of FIG. Both a parameter block table 23a having a configuration equivalent to the table 23a and a registration management block 25a (FIG. 7), which will be described later, are output.

The definition information of the above parameter block is a parameter prepared for the edit exit routine. For example, if the edit exit routine is a line procedure, the definition information of the parameter block is "parameter block name, followed by the network address, and the number of paths (number of logical units). , procedure control parameters (timer value, data length), and if the edit exit routine is terminal control, it similarly contains the "parameter block name followed by the terminal model code, terminal pass number, This is information that defines procedure control parameters (timer value, data length). Further, the registration definition information of the edit exit routine is "ON/OFF" flag information prepared corresponding to the number of registration blocks 230.

The generating means 4 generates the "medium type, file position within the medium, number of required parameter blocks and their names" from the instruction information 24, and the definition information 1.
The parameter block table 23 is stored in the specified file on the mass storage medium 200' by checking with the "parameter block definition information" from 3.
After this operation, output the above instruction information 24.
n registered blocks 2 in the registration table 21 by referring to the "edit exit routine call count" from the "edit exit routine call count" and "registration definition information" from the definition information 13.
A registration management block 25 (explained in FIG. 7) consisting of n records 251 having a one-to-one positional correspondence with the package program 20 (FIG. 3) is prepared. For each record corresponding to the edit exit routine calling unit 201, ON or OFF of a flag, which is management data of registered information, is written by registration definition information 13 that indicates whether the edit exit routine is necessary or not, and the above-mentioned parameter block is written.・Add to the table and output. On the other hand, in system generation work 1', writing is performed only in the edit exit routine name entry section 232 and parameter block name entry section 234 of the outputted registration table 21, and no writing is performed in the flag section 231 (FIG. 3).

The next block 2' is the package program 20,
The registration table 21 and the edit exit routine data set 22 are stored at addresses α,
This is an operation in which the blocks are placed in β ₁ and γ ₁ (20 to 22 are designated as 20a to 22a), respectively, and transferred to the next block 3'. At this point, the registration table calling unit 201 (FIG. 3) at the address αt position in the package program 20a has a relative position (β _{1 +}
x) is described.

Block 3' is the initialization work of writing a predetermined address in each of the flag section 231, edit exit routine entry address entry section 233, and parameter block entry address entry section 235 in the registration table 21a. The registration table with the above name and address filled in is marked 2.
1b. The operation of block 3' will be explained below.

Block 3' arranges parameter block table 23 from address _δ1 of main storage medium 300 to form parameter block table 23a (7th block table 23a).
25a), and the registration management block 25 added to the parameter block table 23 is placed from address _d1 (see FIG. 7) of the main storage medium 300. Next, the reference address βt of the registration table 21a of each calling unit 201 (FIG. 4) at the address _αt position in the package program 20a is rewritten from the relative address β ^R _t to the absolute address β ^A _t , and becomes 20b. .

Next, the state of the flag in the record 251 at each address _dt position of the registration management block 25a is checked, and if the flag is "ON", the address βt of the registration table 21a that has a positional relationship with the registration management block 25a is checked. Set the flag section 231 from "ON". Next, since the edit exit routine data set 22a is arranged from address _γ1 of the main storage medium 300, and the parameter block table 23a is also arranged from _δ1 , the edit exit routine entry address is written. Section 233 and parameter block entry
The registration of all the information in the registration table 21 is completed by writing in the address entry section 235 using the same procedure as described in the prior art 21b.

According to this embodiment, it is possible to change the registration table and the parameter block referred to by the package program without relying on system generation.

According to the present invention, the generation of a parameter block containing editing parameters and the generation of registration information in a registration table are independent of system generation, so the installation status of terminals can be freely designed for each computer system installation location. Furthermore, it is possible to patch parameter blocks from the host computer as needed even during daily work.
