Abstract

PURPOSE:To judge whether a load module is made transient properly or not by displaying a file name, module name, and index on a display part every time a module is accessed. CONSTITUTION:A processor 1 reads a transient control program 12 according to an indication of an application program 11 and reads a necessary load module out of a main storage 10 on the basis of an indication of the program 12 when it is present. When not, a floppy control part 6 is controlled to read a target load module out of a floppy disk 7 and the module is stored in the main storage 10. At this time, when the program 12 generates a request to store the load module in the main storage 10, the processor 1 extracts the file name, module name, and index of the load module from the request on the basis of the indication of a vector table 13. Then, a display control part 4 is controlled to display them on the display part 5.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for displaying file access frequency in a device having a relatively small main memory capacity, and in particular a method for displaying frequently accessed load modules. The present invention relates to a load module display method that improves the processing efficiency of a device.

For example, in devices with a relatively small main memory capacity, such as so-called intelligent terminal devices, it is not possible to store many programs permanently in the main memory, so programs are stored in files such as floppy disks and can be downloaded as needed. Access the file, read the target load module, store it in main memory, and process it.

In devices with many non-resident modules stored in this file, file access occurs frequently to read non-resident modules into main memory, but the same load module may be accessed many times, and the device It is desirable to reduce the frequency to improve processing efficiency.

[Conventional technology]

FIG. 2 is a block diagram of a circuit showing an example of an intelligent terminal device.

The processor 1 reads a program from the main memory 10 and operates. Further, commands are input via the keyboard control section 2 from the keyboard 3 operated by the operator. processor 1
executes the job based on this instruction.

If there is data to be displayed under the control of the processor 1, the display control section 4 reads the data from the main memory 10 and displays it on the display section 5. Similarly, the printer control unit 8 reads data from the main memory 10 and sends it to the printer 9 for printing.

The floppy controller 6 writes/reads the load module to/from the floppy disk 7 under the control of the processor 1 .

FIG. 3 is a diagram illustrating transfer of a load module between the conventional main memory 10 and the floppy disk 7.

The processor 1 shown in FIG. 2 reads the non-resident control program 12 according to instructions from the application program 11, and reads out the necessary load module if it exists in the main memory 10 based on the instructions from the non-resident control program 12.

If the required load module is, for example, module C
Then, the load modules existing in the main memory 10 are modules A and B in this example, and if the required load module does not exist, the floppy controller 6 is controlled to retrieve the target from the floppy disk 7. The load module is read and stored in the main memory IO. That is, since the area of buffer #2 in pool #0 of the main memory is unused, it is stored as module C, and then read and processed.

[Problem that the invention seeks to solve]

Conventionally, since the operation is as described above, the file name, module name, etc. of the load module loaded from the floppy disk in the main memory are not displayed, and the operator does not know it at all.

That is, the operator has a disadvantage in that he is unable to make an appropriate judgment as to whether the load module should be turned into an emergency frog.

[Means for solving problems]

The above problem is that the system is equipped with a storage section, a file section, and a display section.
In a system that stores and processes at least a load module in the file section, means is provided for extracting the file name, module name, and index of the module stored in the file section, and each time the module is accessed, the display section is displayed. This problem is solved by the load module display method according to the present invention, which displays the file name, module name, and index.

[Effect]

That is, in order to display the file name, module name, and index of the non-resident module, a means for extracting them is provided, and the extracted information is displayed each time the file is accessed.

By doing this, if the same load module is frequently accessed, the operator can know its file name, module name, and index, making it possible to set an optimal environment for non-resident control. That is, it can be used as a guideline for determining whether a load module is resident or non-resident, a guideline for determining a pool number (range number on main memory), etc.

Therefore, by setting the optimum environment according to an operator's command, it is possible to reduce the file access frequency and improve the processing performance of the apparatus.

〔Example〕

FIG. 1 is a block diagram illustrating one embodiment of the present invention.

The processor 1 shown in FIG. 2 reads the non-resident control program 12 according to the instructions from the application program 11, and based on the instructions from the non-resident control program 12, determines whether the required load module exists in the main memory 10 shown in FIG. Read it out.

If the required load module does not exist in the main memory 10, the floppy controller 6 is controlled to read the desired load module from the floppy disk 7 and store it in the main memory 10.

At this time, when a request to store a load module in the main memory 10 is issued from the non-resident control program 12, the processor 1 shown in FIG. Extract the file name, module name, and index of. Then, the display control section 4 is controlled to display on the display section 5.

Note that this display uses the bottom line of the screen, which has relatively little influence on other display contents.

〔Effect of the invention〕

As described above, the present invention notifies the operator of load modules whose files are frequently accessed, so that the optimal non-resident design of load modules can be efficiently implemented through operator intervention.
