Abstract

PURPOSE:To reduce storage capacity by storing ruled line sequence data as the format of abbreviated codes. CONSTITUTION:When the kinds of patterns used in a ruled line picture is small, an abbreviated code is used instead of a hexadecimal two-digit code. For instance, the ruled line picture is decomposed into vertical ruled lines and horizontal ruled lines, the existence and inexistence of vertical ruled line character H are respectively expressed by abbreviated codes '1' and '0' and the existence and inexistence of a horizontal ruled line character B are respectively expressed by abbreviated codes '1' and '0', so that arrays shown in Fig.(c) and (d). In reading out the four bits in horizontal direction with a hexadecimal code, the abbreviated code sequence can be obtained as shown Fig(e). Consequently, a simple ruled line picture can be stored in the storage area of small capacity.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for storing a ruled line screen.

[Prior Art] There are various methods for creating and storing a ruled line screen, but the method for creating and storing a ruled line screen that is the subject of this invention is as follows.
Limit the method to using ruled line characters.

FIG. 5 is a diagram showing a part of a ruled line character and a corresponding ruled line pattern, in which the key field shows the type of character key on the keyboard, and the hexadecimal field shows the two hexadecimal digits input by this key. The digital code and pattern column shows the ruled line pattern corresponding to the digital code when this two-digit hexadecimal code is known to represent a ruled line pattern. The character displayed on the key corresponding to the ruled line pattern and the code input by this key are both called a ruled line character.

The display screen of a display device that displays a ruled line screen is, for example,
It is divided into unit sections of 24 rows and 80 units, and if you move the cursor to the desired section on the display screen and input by operating the character keys on the keyboard, a ruled line pattern will be displayed in the unit section on the display screen. At the same time, a two-digit hexadecimal code corresponding to the pattern is stored at the address indicating the position of the unit section.

Creation of a ruled line screen is done in an interactive manner between the creator and the calculator, and the operation of the calculator is controlled by a program stored in the calculator in advance, and the creator's work is to select which program to start by pressing a function key. , and input the data necessary to run the program using the character keys.

Figures 6 and 7 are flowcharts showing the conventional method.
(61) to (70) and (71) to (73) indicate each step. Steps (62), (64), (65), (
In steps 66) and (68), the computer displays questions to the creator on a screen) and executes each program according to the creator's instructions.

It is equipped with programs for not only creating and changing ruled line screens (63), but also moving, copying (67), and inspecting (6). Figure 8 shows the display on the display screen in the case of movement. When you call up and enter S, E, and M in their respective positions, the calculator performs the necessary processing and returns number 8.
The ruled line screen shown in Figure (b) is displayed.

In the step of recording the ruled line screen (70), a two-digit hexadecimal code corresponding to the pattern shown in FIG. 5 is recorded at the address position corresponding to the address of the unit section and stored in an auxiliary storage device (for example, a floppy disk).

When specifying a registration number for a ruled line screen and displaying it on the display screen, convert the string of two-digit hexadecimal digital codes read from the floppy disk in step (73) (this is called ruled line sequence data) into a ruled line pattern. displayed on the display screen.

[Problem to be Solved by the Invention 1] As mentioned above, in the conventional method, a 2-digit hexadecimal digital code is required to store the ruled line pattern of a unit area, and it is difficult to store a relatively simple ruled line screen. There was a problem that a relatively large capacity storage area was required.

This invention was made to solve the above-mentioned problems in the conventional apparatus, and it is possible to store a simple ruled line screen in a small storage area.

[Means for solving the problem] In this invention, when the type of pattern used in one ruled line screen is a decimal number, an abbreviated code is used instead of using a 2-digit hexadecimal code. did.

[Effect] On a ruled line screen that consists of only two types of patterns,
These two types of patterns are 1-bit shortened code rQ.
, rl.

[Example code] The present invention will be described in detail below with reference to the drawings.

FIG. 3 is a diagram illustrating the invention in detail. The ruled line screen shown in (a) is stored by the arrangement of ruled line characters (ruled line sequence data) shown in (b), and the types of ruled line characters are A and @. There are only two types, A is "1", @
Even if it is expressed by one bit as [Oj, confusion will not occur.

However, if you memorize the correspondence table in which "1" is A and "0" is @, you can easily convert it to the original ruled line character. If such a shortened code is used, the length of the code can be compressed to ⅛ in the example shown in FIG.

If there are four types of ruled line characters included in the ruled line screen, confusion will not occur with the 2-bit abbreviation code.

FIG. 4 is a diagram illustrating another embodiment of the present invention, (a)
is a ruled line screen, (b) is the type of ruled line character that exists on this ruled line screen, (C) and (d) are separated into vertical ruled lines and horizontal ruled lines, respectively, and B and H are set to "1" and blank (@
) is represented by "0", and (e) indicates a shortened code.

The ruled line screen shown in Fig. 4 is divided into vertical ruled lines and horizontal ruled lines. For vertical ruled lines, the presence of ruled line character H is set to "1", and its absence is set to "0", and for horizontal ruled lines, the presence of ruled line character B is set to "0".
If the absence of ``1'' is represented by the abbreviated code ``0'', it is shown in Figure 4 (C).
, (d), and by reading the 4 horizontal bits in hexadecimal, the shortened code sequence shown in FIG. 4(e) is obtained.

It is clear that the ruled line screen shown in Figure 8 can be broken down into vertical ruled lines and horizontal ruled lines to create a shortened code similar to that shown in Figure 4, as in Figure 4. Screens can be memorized using abbreviated codes.

FIGS. 1 and 2 are flowcharts showing the method of the present invention, including (11) to (14) and (21).

(22) represents each step. Step (11
) to (14) enter step (70) in FIG. 6, and steps (21) and (22) enter step (73) in FIG. That is, when storing on a floppy disk or the like, it is converted into an abbreviated code, and when displayed, it is converted into ruled line characters and the corresponding pattern is read out.

[Effects of the Invention] As described above, according to the present invention, since the ruled line sequence data is stored in the form of a shortened code, there is an effect that the storage capacity can be reduced.
