Abstract

PURPOSE:To simplify the coupling to a single load module and also to simplify the operation and the debug of a program by using a module table in order to recognize the head addresses and the sizes of plural load modules. CONSTITUTION:A processing system consists of a working station which includes a CPU 1, a memory 2, a keyboard 3, a display 4, and a magnetic tape 5. Then a system file of a 1st load module is connected to a station data file of a 2nd load module for the production of an exchange file of a 3rd module. These three modules consist of a library control list LD, an original table OTL, and plural sections SEC respectively. Each SEC consists of a module control list MCD and a text TEXT. When these three modules are connected to each other, the 1st module is attached to the device 5 and the module names are inputted via a keyboard 3 according to the instructions given from a display 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a load module combination scheme, and more particularly to a load module combination scheme using a module table to create an operating file such as an exchange file.

[Conventional technology]

Among the data used by electronic exchanges to perform exchange processing, data that is given in a fixed manner and is not affected by station conditions is called system data. System data is the configuration of the exchange system.

The arrangement and allocation of programs in memory are data that indicate the status and the like. A system file (first load module) stores the above-mentioned system data to which an absolute address has been assigned in order to arrange it on the memory.

In addition, among the data used for exchange processing, the exchange
(station conditions) is called station data. Station data is created so that the hardware configuration of each station can be used as data by the program when proceeding with the exchange process.
There are frame configurations, number of subscriber terminals, trunk types, etc. A file in which absolute addresses are assigned and stored in order to arrange this station data on the memory is called a station data file (second load module).

When creating an exchange file (third load module) by combining the first load module and the second load module, in the conventional load module combination method, the job control language ( By activating the linkage editor using JCL) and specifying the file combination order and file start address, a plurality of files in memory are combined in memory and one third load module is created.

FIG. 5 schematically shows the coupled state of the load modules described above.

[Problem to be solved by the invention]

In the conventional load module coupling method described above,
The JCL instructions are complex, and not only a large capacity memory is required to create the third load module on the file memory, but also software center equipment is required to start the linkage editor.

The present invention has a small capacity memory and is easy to operate.
It is an object of the present invention to provide a load module combination method that can create a third load module on storage media such as various magnetic tapes.

[Means for Solving the Problems] The load module combination method of the present invention uses a module table to recognize the start address and size of a plurality of load modules, thereby combining them into one load module.

〔Example〕

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

FIG. 1 is a block diagram showing a processing system in an embodiment of the present invention, and FIG. 2 is a flowchart showing a processing procedure in the embodiment. Also, Figure 3 (A) and (B)
, (C) and (D) are diagrams showing the configuration of a load module in the same embodiment, and FIG. 4 is a diagram showing the configuration of a module table chain in the same embodiment.

The processing system shown in Figure 1 includes a central processing unit 1, a memory 2
．． Keyboard 3. Display 4 and magnetic tape device 5
This is a workstation that combines the system file of the first load module and the station data file of the second load module to create the exchange file of the third load module.

1st. The second and third load modules (LM) each have a library management directory (LD) and an origin file (LD).
OTL) and multiple sections (SEC). Each section (sEc) consists of a module management record (MCD) and text (TEXT). Furthermore, the library management book (LD), origin table (OTL), and module management book (MCD) have the formats shown in FIGS. 3(B), (C), and (D), respectively.

When creating a third load module by combining the first load module and the second load module, the operator attaches the first load module to the magnetic tape device 5 and follows the instructions displayed on the display 4. Enter the module name of the load module from keyboard 3 (
sl).

As a result, the central processing unit 1 creates a module table using the memory 2 (S2), and performs MT reading and memory writing (S3). Repeat the above process until all load modules to be combined are written to memory 2 (S4)
. Thereby, a module table is configured in the memory 2.

Next, when the connection order (module name) is entered from the keyboard 3 (S5), the central processing unit 1 creates a module table chain (S6), and performs memory reading and MT writing in accordance with the connection order (S7). Repeat for all specified module names (S8). As a result, one load module is created.

〔Effect of the invention〕

As explained above, according to the present invention, by combining multiple modules without being aware of the module start address and memory size, it is possible to reduce the amount of memory used for combining, and there is no need for a linkage editor. This eliminates the need for a software center. As a result, running and debugging the program is also significantly easier.
