Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a character string display device of the present invention.

As shown in FIG. 1, the character string display device according to the present embodiment has a keyboard 1, a display section 8 which is displayed on the screen when display information is received, and a definition which stores definition information described later in advance. When a display start command is input from the information storage means 3 and the keyboard 1 described above, the definition information storage means 3 described above is input.
From the control unit 2 which reads the definition information in the order of storage from the definition information at an appropriate predetermined time interval, and for every screen display command used, interprets the contents of the specified operand corresponding to each command The instruction interpreting unit storing means 7 storing a program to be executed and output as display information, and the start address of the program for each instruction described above stored in the instruction interpreting unit storing means 7 are associated with the above instruction. When the output is received from the stored address storage unit 5 and the control unit 2, the address corresponding to the instruction in the received definition information is extracted from the address storage unit 5 described above, and the address extracted together with the added definition information is extracted. And a corresponding command is not present in the address storage means 5, a predetermined error information is output to the display unit 8 as display information. The program starting at the address included in the output from the disconnection unit 4 and the instruction determination unit 4 is read from the instruction interpretation unit storage unit 7 described above, and the operand included in the definition information input from the instruction determination unit 4 is read out as described above. Execute the read program passed to the program,
It is composed of an instruction interpreting section extraction executing means 6 for outputting the result to the display section 8.

In the definition information storage unit 3, as shown in FIG. 2, an instruction and an operand related to this operand are associated with each other and stored in the order in which the instruction is input. For example, the CLR shown in FIG.
Is an instruction to erase the image that has been displayed on the screen until then, and FDIN, which is the instruction in FIG. 2, is a fade-in,
That is, it is an instruction to display the image in a display format in which the display is gradually brightened until it reaches the normal brightness with the passage of time, and is associated with the FDIN which is the instruction to display the operand. The X coordinate of the display position of the first character of the character string on the screen, the Y coordinate of the display position, the color of the character string to be displayed, and the normal brightness after the execution of this command is started. The change time required until the character string is displayed and the character string to be displayed by this command are stored in this order, separated by ",".

In addition, the instruction shown in FIG.
T is an instruction that specifies that this command will not be completely displayed at the change time stored in association with it after being activated, and the target character string is displayed at the change time specified in the operand. It is an instruction in the form of being erased.

Further, the instruction EN shown in FIG. 2 is
This instruction indicates the completion of image display, and this instruction does not require an operand as in the above-described instruction CLR.
It should be noted that CLR, which is the instruction already described, does not require a corresponding operand. In addition to the above-mentioned commands, it is sufficient to prepare in advance for the number of displays that require commands that define other processing for displaying a character string on the screen.

In the address storage means 5, as shown in FIG. 3, the instruction interpreter storage means 7 which stores the programs corresponding to the respective instructions described in FIG. 2 is stored. The start address of the program that executes each instruction is stored in association with this instruction.

When a display start command is input from the keyboard 1, the control unit 2 defines the definition information in units of definition information at predetermined time intervals according to a built-in program (not shown). The information is read from the information storage means 3 in the order of storage and is output to the instruction determination section 4.

In this process, if the corresponding instruction does not exist in the address storage means 5, predetermined error information is output to the display section 8 as display information.

The instruction judging section 4 refers to the address storage means 5 to extract the address stored in association with the instruction included in the input definition information, and interprets the instruction together with the input definition information. It is output to the copy extraction executing means 6.

The instruction interpreting section extraction executing means 6 includes an instruction judging section 4
When the output from the instruction interpreter is received, the program starting at the address included in the output from the instruction determiner 4 is read by referring to the instruction interpreter storage 7, and the operand included in the input definition information is read out. Handed over to the program,
The read program is executed and the result is output to the display unit 8 as display information.

By the above operation, the character information included in the operand in the definition information can be displayed on the display unit in the format according to the instruction included in the definition information.

[0019]

As described above, according to the character string display device of the present invention, a command for displaying a screen for designating a process for displaying a character string in a screen display format defined in advance is provided in the required number of types. It is prepared in advance, and a program for executing processing corresponding to such an instruction is stored in advance in the instruction interpreting unit storage means, and such an instruction and operands required for this instruction are defined. When information is created for each command, and the created definition information is stored in advance in the definition information storage means in the order in which it is desired to be displayed and displayed,
The definition information is sequentially retrieved from the definition information storage means,
In order to execute the program, a program for the above-mentioned dedicated instruction for displaying the character string is created in advance for each instruction. Therefore, the above-mentioned instruction and the necessary operand corresponding to this instruction are created in the display order. Since it can be stored as definition information, it is sufficient to create definition information instead of a program that creates a character string as in the past, and such definition information is created in the language created for the conventional program. The effect that it is easier than creating a program using the instructions provided in it and that such definition information can be created easily by a person other than a specialized programmer, and the definition The time required to create information can be shorter than the time required to create a character string display program created for conventional devices of this type. And a fruit.
