Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program starting method and system for starting a desired program in a computer, and more particularly to a program starting method and system suitable for a word processor dedicated machine.

[0002]

2. Description of the Related Art Various types of computer devices, for example, dedicated word processors are known, and are generally configured as shown in FIG. In the figure,
A word processor program, a monitor or load program, CG, etc. are stored in the ROM 10. Normally, the CPU 12 is turned on when the power switch is turned on.
It is loaded and started by. Note that these programs or some of them may be expanded in the program area 14A of the system area of the RAM 14 depending on the system. At the time of startup, necessary initialization processing and word processor program startup (loading) processing are performed.

Next, the CPU 12 instructs the display device 16 to display, for example, a menu screen or a new document creation screen by this activation. The operator looks at the display device 16 and looks at the keyboard 18
Input the necessary processing instructions and text by operating the above keys. For example, when the text data already stored in the FD is read and displayed on the display device 16, the corresponding FD 20 is set in the drive device 22 and an instruction to that effect is given on the menu screen.

Then, the drive unit 22 is driven by the CPU 12, and desired text data is read and stored in the data area 14B of the RAM 14. At the same time, for example, the first page data of the text data is output to the display device 16 and displayed. During processing by the CPU 12, the work area 14C of the system area in the RAM 14 is used as necessary.

The text data created by the key operation on the keyboard 16 is stored in the data area 14B of the RAM 14. This text data is stored in the FD 20 of the drive device 22 or printed out by the printer 24 based on the key operation by the operator.

[0006]

By the way, such a word processor dedicated machine normally has only a function as a word processor, and is not intended to execute various programs like a personal computer.

In particular, in the case of a simple model used in general households (hereinafter, simply referred to as "household"), for example, RAM1
The capacity of 4 is several tens of kilobytes, which is very small compared to several hundreds of kilobytes in a personal computer or the like. This is because the purpose-built word processor for home use is intended to create relatively short document data with a relatively simple document processing function, and it can execute programs with rich functions such as word processor models for business and personal computers. This is because it is not intended.

By the way, various programs provided for personal computers and the like generally have a capacity of about several hundred kilobytes, although the capacity of the programs varies, and the capacity tends to increase in recent years. Therefore, such software cannot be directly applied to a home word processor dedicated machine. On the other hand, in recent years, there has been a tendency for word processor users to demand various functions as well as simple document creation, and there has been a demand for a program operable on a dedicated word processor for home use.

It is an object of the present invention to provide a program execution method and its system capable of easily executing a program other than a word processor in a home word processor dedicated machine. To do.

[0010]

According to the present invention,
The application program to be executed is divided into a plurality of files in consideration of the capacity of the main memory of the dedicated word processor for home use. The plurality of files are stored in the auxiliary storage device. Then, of these, the main file is first read and executed at startup. The main file resides in the main storage device and controls subsequent operations. Other files are read from the auxiliary storage device to the main storage device and executed as necessary according to the instructions of the main file.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. The same reference numerals are used for the same or corresponding components as those in the conventional example described above.

FIG. 1 shows the configuration of a dedicated home word processor dedicated to the present invention. As shown in the figure, the hardware configuration is exactly the same as that in FIG. A program to be executed, for example, accounting, accounting, communication, spreadsheet, database, game, or various programs (hereinafter referred to as “application program”) such as an integrated type thereof, includes a main file 32 and a plurality of sub-files 34A. , ..., F divided into 34N
Each is stored in D30.

Next, the files stored in the FD 30 are divided in consideration of the memory capacity in the RAM 14. As described above, the RAM 14 has the normal program area 14A, the data area 14B, and the work area 14C. In this embodiment, the main file 32 resides in the program area 14A, as will be described later. In addition, depending on the content of the application program, how much data area 14B
It is determined whether or not the work area 14C is required. Further, in some cases, a part of the program in the ROM 10 is a RAM.
It may be expanded in 14 program areas 14A. Therefore, each of the sub-files 34A, ..., 34N is divided and configured so that the capacity falls within the free capacity range obtained by subtracting those capacities from the total storage capacity of the RAM 14.

For example, assume that the application program is accounting software. In general accounting, the main work is to create journals such as journals, income statements, account ledgers, financial statements and balance sheets. Therefore, for example, subfiles 34A, 34B, ..., 34C are created for each form. These subfiles 34A, 34B, ...
, 34C each include a basic form format of the corresponding form, processing functions such as data input, calculation, and printout.

Next, the main file 32 is set to be read and activated first when the file is read from the drive device 22. This main file 32 includes sub-files 34A, 34B, ..., 34
The processing in N is integrated, and reading and starting of these sub-files 34A, 34B, ..., 34N are performed by this main file 32.

Next, the operation of this embodiment will be described.
First, the dedicated word processor is placed in a menu screen display state as a normal word processor, for example. In this state, among the program files of the word processor stored in the ROM 10, a basic one such as a character input file is activated.
Normally, in a home-use word processor dedicated machine, a function capable of starting a program stored in the FD is supplementarily prepared in the loading program stored in the ROM 10, so that the function is selected by the operator.

Then, the loading program is executed in the CPU 12 to drive the drive device 22, and the file is read from the FD 30 set in advance. In this embodiment, the main file 32 is read first and the program area 14A of the RAM 14 is read.
Be deployed to. As described above, the capacity of the main file 32 is set in consideration of the storage capacity of the RAM 14, so that the reading can be performed smoothly. As a result, the application program is activated and its operation can be executed. In this state, for example, in the case of accounting software, a menu screen for selecting each form will be displayed.

The operator operates the corresponding key on the keyboard 18 while referring to the display device 16, and the required processing is executed. At this time, the sub files 34A, 34B, ... Are instructed by the operator.
, 34N, the corresponding subfile 34n is replaced by the main file 32.
It is read from the FD 30 based on the instruction. This sub file 34n is stored in the program area 14 of the RAM 14.
Expanded to A. Also in this case, since the capacity of the sub-file 34n is set in consideration of the storage capacity of the RAM 14 as described above, the reading can be performed smoothly.

For example, during execution of accounting software,
When the journal diary creation process is performed, the corresponding subfile is read from the FD 30 and executed.
In addition, when a settlement report is created, a subfile corresponding to it is read from the FD 30 and executed.

In this way, the subfiles 34A, 34A
Necessary ones of B, ..., 34N are read from the FD 30 and activated, so that various application programs can be executed even with a dedicated home word processor. The input data is RA
The data is stored in the data area 14B of the M14, FD30 (in some cases, another FD created for data storage), or printed out. The data in the RAM 14 are collectively stored in the FD 30 when the application program ends according to an instruction from the operator.

By the way, in the case of accounting, for example,
It is common to organize and save printed out forms. Therefore, in this embodiment, the thermal paper 42 having the binding holes 40 as shown in FIG. 2 is used as the print-out paper. For example, 30 binding holes 40 are provided. In this case, due to the binding holes 40, the print area on the thermal paper 42 is limited as shown by the broken line in the figure. Therefore, the printout must be formatted so that it falls within this range.

Therefore, for example, in each of the sub-files 34A, 34B, ..., 34N corresponding to various forms, a format for the thermal paper 42 having such binding holes 40 is prepared in advance, and a printout is made based on this Try to do it. As a result, it becomes possible to satisfactorily print out and save the form regardless of the presence of the binding hole 40.

The present invention is not limited to the above-described embodiment, but various design changes are possible, including the following, for example. (1) Depending on the model of the word processor, when the FD 30 is set in the drive device 22 and the power is turned on, the FD 30
The loading program may be configured to preferentially access 30, and it is similarly applicable to such a case.

(2) The work sharing of the main file and the sub-file may be appropriately set as necessary. However, as described above, the main file 32 is a program resident in the RAM 14. Therefore, the smaller the capacity, the data area 14B and work area 14 of the RAM 14
C can be large. For this purpose, for example, the main file 32 is designed to perform only the simple processing of reading and starting the required sub files,
Other processing should be left to subfiles. (3) The present invention includes accounting, accounting, communication, spreadsheet,
It can be applied to various application programs such as databases, games, and integrated types thereof.

[0025]

As described above, according to the program execution method and the system thereof according to the present invention, a desired application program is divided into a plurality of files in consideration of the main storage capacity and is resident in the main storage device. Since any one of the necessary sub-files is selected and read and executed by the main file to be executed, there is an effect that various application programs can be executed even in a home word processor dedicated machine.
