Abstract

PURPOSE:To shorten the program loading time to a memory and to facilitate the character processing work of this character processor by selecting and designating freely the program file of the function required by the operator when a program file is loaded into such an internal memory as RAM disk. CONSTITUTION:A displaying means 3 which displays the names of program files stored in an external storage device is provided. In addition, a designating means 1 which can designate the names of plural programs to be loaded among the file names displayed by the means 3 and a loading means 4 which loads the files designated by the means 1 into the internal storage device from the external storage device are also provided. Accordingly, the program files to be loaded into such an internal memory as RAM disk can be selected and designated freely by the operator. Therefor, the probability of the presence of the function required by the operator in the internal memory becomes larger and, at the same time, the loading time of an unnecessary file can be eliminated. Thus, the operability of this character processor can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character processing device, and more specifically, a character processing device that performs a process of loading a program file stored in an external storage device onto an internal memory such as a RAM disk. The present invention relates to a character processing device capable of processing characters.

[Prior Art] Conventionally, there have been character processing devices that can load program files stored on an FD (floppy disk) or HD (hard disk) into a so-called RAM disk made of semiconductor memory.

[Problem to be Solved by the Invention] However, in the conventional device as described above, when loading a system program file into a RAM disk, a predetermined function ρ program file is loaded, regardless of the function used by the operator. Since the functions required by the operator were only loaded on the RAM disk, there was a low probability that the functions needed by the operator would exist on the RAM disk (and there was a drawback that operability was poor because they often had to be read from the outside).

It is an object of the present invention to provide a character processing device that eliminates the above-mentioned drawbacks, allows an operator to freely select and specify program files to be loaded into an internal memory such as a RAM disk, and improves operability. It is about providing.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a display means for displaying the file name of a program file stored in an external storage device, and a display means for displaying the file name displayed by the display means. The present invention is characterized by comprising a designating means that can select and designate a plurality of program file names to be loaded, and a loading means that loads a file designated by the designating means from an external storage device to an internal memory.

Further, as an example of its aspect, the present invention includes, for each file specified by the specifying means, a canceling means for canceling the designation, and a storage means for storing specified file information indicating the status of the specification by the specifying means. It is characterized by

[Function] Since the present invention allows the operator to freely select and specify program files to be loaded into an internal memory such as a RAM disk, the probability that the function required by the operator exists in the internal memory is reduced. is high (and also eliminates unnecessary file loading time, improving operability.

Similarly, the area 52 shows a state in which file names from "Document Catalog" to "Registered Words - List J" are stored.

Next, the operational procedure of the file designation process according to the embodiment of the present invention will be described in detail with reference to the flowcharts of FIGS. 7 and 8. This program is stored in the ROM 14. After the initial program loader (IPL) is completed, first, in step Sl, the directory information stored in the floppy disk is read from the floppy disk drive device 13, and the load specified data area 18 of the RAM 15 is loaded.
write to. Next, the load designation area 53 is cleared to 0 (see FIG. 6), and the process proceeds to step S2.

In step S2, the CRT is loaded based on the load specification data 50.
A list of program file names is displayed on the display screen of II as shown in FIG. 4(A). At this time, the cursor 42 is located at the top of the load specification parameter 41 (the fourth
(See figure (A)). Next, the process proceeds to step S3, and it is checked whether there is any key force from the keyboard KB12, and if there is key force, the process proceeds to step S4, where a key code is captured.

In step S4, the captured key code is determined. If it is "0", the process advances to step S5; if it is "1", the process advances to step S6; if the cursor down key (CD) 34, the process advances to step S7; (CU)3
If it is 3, proceed to step S8 and press the load execution key (EX).
If the key code is 35, the process advances to step S9, and if it is any other key code, the process returns to step S3, where the key code is on standby.

In step S5, the load designation parameter at the cursor position displayed on the CRTII is set to 0, and the cursor is displayed one step below. At the same time, the load designation area 53 corresponding to the same file name in the load designation data area 18 of the RAM 15 is also set to 0 (see FIG. 6), and the process returns to step S3.

In step S6, as in step S5, CRTII
The load designation parameter at the cursor position displayed in is set to 1, and the cursor position is displayed one step below (see FIG. 4(B)). At the same time, the load specification area of the load specification data area 53 of the RAM 15 is also set to 1,
Return to step S3.

In step S7, if the cursor 42 is at the lowest position, nothing is done, and if it is not at the lowest position, the cursor 42 is moved down one stage and the process returns to step S3.

In step S8, if the cursor 42 is at the topmost position, nothing is done, and if it is not at the topmost position, the cursor 42 is moved up one stage and the process returns to step S3.

In step S9, the RAM disk 1, which will be described later in FIG.
7 is performed, and the process ends.

The flowchart of FIG. 8 shows details of the order of operators in the loading process to the RAM disk 17 shown in step S9 of FIG.

The procedure of this process shows the operation when the load execution key 35 is pressed after the designation of the file to be loaded into the RAM disk 17 is completed.

First, in step S91, 1 is set in the cursor register 19 existing in the RAM 15, and the process proceeds to step S92. In step S92, whether there is a load designation for the file number indicated by the cursor register 19 (1) or 0 if there is no load designation.
), and if yes (1), the process advances to step S93. On the other hand, if it is 0), the process advances to step S94.

In step S93, the file numbered by the cursor register 19 is read from the floppy disk device FDD13 and loaded onto the RAM disk 17. After this loading, the process advances to step S94.

In step S94, the value of the cursor register 19 is incremented by 1, and the process proceeds to step S95. In step 395,
It is determined whether the value of the cursor register 19 is equal to the number of files 51, and if they are equal, the process returns to the main routine (not shown). On the other hand, if they are not equal, the process returns to step S92.

In this embodiment described above, the initial program loader (I
After completing the program (PL), the operator specifies the program files to be loaded into the RAM disk and loads them all at once, but now it is now possible to load individual files immediately after they are specified. It can also be configured.

It is also possible to store the load designation information of a file designated to be loaded in a non-volatile external storage device, and to load the file to the RAM disk based on this information at the time of IPL.

Furthermore, it is also possible to add, change, or cancel the load designation information stored in the external storage device later.

[Effects of the Invention] As explained above, according to the present invention, when loading a program file into an internal memory such as a RAM disk, an operator can select and specify a program file with a desired function. RA
The time required to load a program into an internal memory such as an M disk is shortened, which not only makes work easier, but also significantly reduces work time.
