JPH03137719A - Initialization method in information processor - Google Patents

Abstract

PURPOSE:To prevent the deletion of a program following initialization by checking whether a prescribed external storage medium is initialized or not and writing an initial value into a data part when the program exists in the medium. CONSTITUTION:There is a case when FD5 loaded on a floppy disk driver (FDD) 4 is initialized and a case when it is not. When a loaded file is initialized, it is judged whether the program which cannot be copied is present or not. When it is present, the initial value is written into the data part in the program part of the file. When the file is not initialized, the file is made into a format. When initialization terminates or the file is initialized, key-in data from a keyboard 1 and data-processed information are stored in the data part of the file is necessary. Data is displayed on the screen of CRT 11 at that time and prescribed output information is printed on a paper 13 by a printer 12.

Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to the initialization of a file in an information processing device, and when a program is stored in an optional external recording medium at the time of initialization of the file. The present invention relates to an initialization method that includes a function to determine whether the program is protected or the data section is initialized.

(b) Conventional technology Generally, personal computers (
Hard disks (H
D) or floppy disks (FD) are often used. Particularly in word processors, FDs are often used because -C is inexpensive and easy to use. This FD
When a-ding a file using a word processor, if it is unused or has been initialized in a different format, be sure to initialize it and input the specified document or drawing data to create a specified file.

As an example of the above initialization, as shown in the instruction manual for the word processor 5WP-340 published by Sanyo Electric Co., Ltd., as an external recording medium, if it can be initialized by hardware, the contents can be Whatever it was, it was being initialized.

(C) Problems to be Solved by the Invention In the conventional example described above, the file to be initialized contains a program that cannot be copied at the user level (
(registered), they would be erased by initialization, causing fatal damage to the user.

(Means for Solving the Problems) The present invention provides human power means for inputting data, information for processing the data input by the input means, and predetermined information corresponding to a program section stored in the external recording medium. is recorded on the recording medium, and after reading out the predetermined information, an initial value is written in the data section of the recording medium.

(*) Effect: In the method of the present invention, a predetermined external storage medium is checked to see whether it has been initialized or not, and if a program exists in the medium, an initial value is written to the data section, so that the medium is valid. available for use.

To explain the present invention according to the embodiment drawings, the first (50) is a block diagram for explaining the method of the present invention, FIG. 2 is a flowchart of the method, and FIG. 3 is an external storage medium in the method. A file configuration diagram is shown.

In the drawing, (1) is a keyboard as an input means;
(2) is the input control unit, and (3) is the CP as the information processing unit.
U, (4) has a floppy disk driver (FDD) as an external storage device, (5) has a floppy disk (FD) as an external storage medium, and (6) has a data memory section (7) as a buffer memory. first memory,
(8) is a second memory having a program section (9) and a menu part (10); (11) is a CRT as a display section;
, (12) is a printer that prints predetermined characters, etc. on printing paper (13), and (14), (15), and (16) are output control units.

Next, to explain the operation of the method of the present invention, the keyboard (1)
When data is keyed in from the input control section (2), the keyed-in data is added to the CPU (3) via the input control section (2).
After the information is processed by (3), the first memory (6)
The data is temporarily stored in the data memory section (7) in the internal memory.

Here, if necessary, the data stored in the first memory (6) is saved in the FD (5) as an external storage medium by pressing a predetermined key from the keyboard (1>), and the data corresponding to the key-in is saved. Read when data is reused.

There are cases where the FD fully loaded into the FDD (4) is initialized and cases where it is not initialized, and each case will be explained using FIGS. 2 to 4.

First, convert the file FD as an external storage medium to an FDD (4
), the data read out by the FDD (4) is transmitted to the CPU (3), and the flowchart shown in FIG. Process with.

If the loaded file has been initialized according to the above flow, the next step is to determine whether or not a program that cannot be copied exists, and if it exists, the initial value is stored in the data section (17) in Figure 4. is written, and the initialization is completed.

On the other hand, if the file has been initialized, for example, the number xXX (3 digits) and the character string YYY (3 digits) are recorded as the ID string as shown in Figure 3, and in this case, the flowchart shown in Figure 2 Proceed to the N side of , and format the file.

If the initialization has been completed or if the file has been initialized, key-in data from the keyboard (1) and data processed information can be stored in the data section (17) of the file as necessary.

At this time, various displays are displayed on the screen of the CRT (11) serving as a display section, and predetermined output information is printed on printing paper <13) by the printer (12).

In the explanation of the above operation, the Japanese word processor (
In the case of a word processor), after the power is turned on, the contents of the program part (9) and part of the menu (10) in the second memory (8) are read out, the initial menu is displayed on the CRT (11), and the keyboard is pressed. Based on the pressing of the predetermined key in (1), an initialization routine is executed and processing is performed according to the flow chart shown in FIG.

(G) Effects of the Invention According to the initialization method of the present invention, if a program that cannot be copied at the user level is registered in a file of an external storage medium to be initialized, conventionally However, not only are they protected, but it is now possible to write initial values in the data area instead of initializing them, which is extremely effective.
