JPH0215363A - Supporting system for ruled line display - Google Patents

Abstract

PURPOSE:To more simply set up various ruled lines and to rapidly display the set ruled line by including the font data of ruled lines in a Japanese character generator having a RAM. CONSTITUTION:A control part 2 stores specified ruled line font data in a memory 4 and writes a command or the like inputted from an external keyboard in a Japanese character generator KGC static RAM 3 including a RAM on the basis of an instruction from an external interface 1. The control part 2 also writes the font code of the RAM 3 in a graphic VRAM 6 through an internal bus 5. In the case of displaying cross ruled lines on an upper right corner, a terminal, etc., the memory 4 is referred prior to display, a font is composed and the font is reset in the RAM 3 to display the font.

Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to a support system for the positive and negative wires.

[Conventional technology]

Conventionally, gay line display has a fixed R (
'-) Several types of fonts are provided as stored in M. In order to display the C line, the character code was output one by one in the corresponding column in the same way as the general T-character C-1-TE.

[Problem to be solved by the invention]

Since the conventional key line support described above provides the key line in fonts stored in ROM, a wide variety of key line displays cannot be achieved in this manner. Therefore, a program that wants to display a variety of lines must display the lines graphically, which has the disadvantage that the display is much slower than when outputting text. In addition, although it is a simple drawing function, it is not supported at the system command level, so it has the disadvantage that the settings are complicated and the display speed is reduced9 [Means for solving the problem] Support for the line display of the present invention The system includes a static RAM (also known as a static RAM), a Japanese character generator, and a control section having a registration means for registering the line and a setting display means for controlling the line display. be done.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Reference numeral 1 denotes an external interface for registering, setting, and displaying lines. By specifying commands input from an external keyboard, etc. through the interface 1, the control unit 2 stores the specified line font data in the main memory, i.e. Japanese character generator (hereinafter referred to as KGC static RAM) 3 stored in memory 4 and having RAM
I write into it. Also, according to the specification on the external interface 1, the control unit 2 transfers the font code of the KGC static RAM 3 to the graphic VRAM through the internal bus router.
(hereinafter referred to as VRAM) 6 is also performed. If you want to display a cross line such as the upper right corner or edge, refer to memory 4 before displaying and combine the fonts with 1-K G C
Display after resetting the font in static RAM3.

FIG. 2 is an example of the use of font code assignment in the KCC static RAM 3, and the cross code may be changed many times during execution according to the specifications of the external interface.

FIG. 3 is a flowchart showing an example of the operation of the control section 2. As shown in FIG. The control unit 2 analyzes commands specified by the external interface 1 input from a keyboard or the like. In other words, it is determined whether the command specified by the external interface 1 is to be registered as a line (Step 2), and if registration is specified, the command data is copied to the memory 4 in Step 2.
), its contents are set in the KCC static RAM 3, and the registration means 11 is terminated (step 2).

If the judgment result in step ■ is not a key line registration, use step ■ to determine whether it is a setting display command or not. Determine whether it is a line code and determine whether it is a place that should be a cross code (step ■). If it is a cross code, refer to the memory 4 to synthesize the cross font and set it to KCG static RA, M3 (step 2), and output the KCGC static RAM3 font to the screen (step 2). If step (2) indicates that the code is not a cross code, step (2) is skipped and the KCG static RAM 30 font is output to the screen (step (2)). In this manner, the operation of the setting display means 12 is completed.

〔Effect of the invention〕

As explained above, the present invention can provide a variety of font shapes on the text screen by having the font data of the gray line in KCG static R, AM. This has the effect of allowing high-speed display.
