Abstract

PURPOSE:To easily and promptly alter information by altering the information with the use of the information stored into a memory means beforehand. CONSTITUTION:A CPU (central processing unit) 2 operation-controls the whole device through a bus 10. A RAM (random access memory) 4 internally possesses a buffer 4A, which temporarily stores the contents of a file read from a fixed magnetic disk device 8 or a floppy disk device 9, and a table 4B to set a system initial value, and disk devices 8 and 9 store the file (default file), etc. written with the system initial value. When a command for altering the system initial value is input-designated by a keyboard 7, the designated default file is transferred to the buffer 4A in the RAM 4, the contents are analyzed, and set to the initial value table 4B. Thus, the system initial value is altered by a simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character output device, and more particularly, to a character output device having a function of changing system initial value information or the contents of a data file.

(Prior Art) Conventionally, setting of system initial value information in this type of device is done only once when powering up the system.
After the system has started up, it is not possible to change some or all of the system initial value information.

In addition, the input data sent from the host computer was analyzed and image developed as it was before being output, so if there was an error in the print data, the host computer would correct it and convert the corrected print data into a character. It had to be sent back to the output device.

(Problem to be Solved by the Invention) When changing the system initial value information as described above, it is necessary to start up the system by turning on the power again, which takes a considerable amount of time and is not satisfactory in terms of use of the device. It wasn't possible. Furthermore, since the print data is corrected as described above, a lot of time is lost due to the correction of only a few places, which is really inconvenient in terms of use.

An object of the present invention is to solve the above-mentioned problems and provide a character output device that allows information to be changed easily and quickly.

The disk devices 8 and 9 store files (default files) in which system initial value information has not been written. 1
0 is a bus consisting of an address bus, a data bus, and a control bus.

In the above configuration, when the operator inputs and specifies a command for changing the system initial value from the keyboard 7, the specified default file is transferred to the buffer 4A in the M4. After that, analyze the contents and create the initial value table 4.
Set to B.

Next, the operation of this embodiment will be explained in detail with reference to the flowchart in FIG.

In the key input waiting routine that waits for a key input from the keyboard 7, when a key input is received from the keyboard 7,
If the command is an initial value changing command, the command routine shown in FIG. 3 is executed.

First, in step S1, it is determined whether a command input from the keyboard 7 includes a file specification as a parameter. If there is a designation, the process advances to step S2, and it is checked whether the corresponding file exists in the magnetic disk 8 or 9.

If it is determined in step S2 that the corresponding file does not exist, the process advances to step S9 and error display processing is executed. When there is a corresponding file,
In step S4, the contents of the file are read from the magnetic disk 8 or 9, and the contents of the file are read from the buffer 4A in RAMJ.
Transfer to.

If it is determined in step Sl that there is no file designation, the process proceeds to step S3, where a file with a system-fixed name is processed as being designated.

In step S5, the contents of the buffer 4A transferred in step S4 are analyzed. If there is no error in the determination in step S6, the value is set in the system initial value table in the RAM 4 in step S7, and the process ends.

If there is an error in the determination at step S6, the process advances to step S8, where error display processing is performed and the operator waits for a response.

According to this embodiment, the system initial values can be changed by simple operations.

As explained above, in this embodiment, a file containing system initial value information is stored in the storage device in advance, and the contents of the specified default file are read in response to an instruction command from the operator. Since the data can be analyzed and set in the table, there is no need to restart the system from power-on, resulting in a reduction in time.

FIG. 4 shows a circuit configuration of another embodiment of a character output device to which the present invention is applied. In FIG. 4, the same parts as in FIG. 2 are given the same reference numerals. The RAM 4 has an internal data file editing buffer 4C. Reference numeral 11 denotes an input buffer that temporarily stores print data input from the host computer 12. CBr4 displays various statuses during print processing and file contents when editing data files. 13 is a magnetic disk device for storing print data. 14 is an output buffer, which develops an image based on the result of analyzing input data. Reference numeral 15 denotes an output unit, which outputs the contents read from the output buffer 14 onto paper.

Next, the operation of this embodiment will be explained in detail with reference to the flowchart shown in FIG.

When a command is input from the keyboard 7, step 5
In step 11, it is determined whether the command specifies a spool. If the command does not specify a spool, the process advances to step S3 and corresponding processing is performed.

In step 512, the spool file is opened using the command parameter input from the keyboard 7 in step Sll as the spool file name.

Next, the process proceeds to step 514, in which it is determined whether the print data sent from the host computer 12 has been transferred to the input buffer 11. If the print data is in the input buffer, the process advances to step S15, and in step 512 it is written to the ovend file.

Then, proceeding to step 51B, the host computer 12
It is determined whether the unit of print data from .

If the unit of print data is not completed, step 514
If it is the end, it is assumed that one file has ended, and the process proceeds to step 517, where the spool file is closed and the spool process ends.

Next, the process advances to step 518, where it is determined whether a command for modifying the spool file recorded in the magnetic disk device 13 has been input. If a different command is input, corresponding processing is performed in step 521. When a correction command is input, the process proceeds to step 519, and in step 518, the parameters of the correction command inputted from the keyboard 7 are checked, and if an error occurs, the process proceeds to step S20, after which an error display process is performed. In step 518, the computer waits for command input from the keyboard 7.

If it is determined in step 519 that the parameter specification is correct, the process advances to step S22, where the content of the specified file is read from the magnetic disk device 13, and the RAMJ
The data is transferred to the editing buffer 4C inside.

Then, in step S23, the contents of the editing buffer 4C are displayed on the CBr4, and the operator
Use this to make corrections where necessary.

In step S24, it is determined whether or not the modification has been completed. If the modification has been completed, a process is performed in which the contents of the editing buffer 4C are written back to the magnetic disk device 13 in step 525.

After completing this process, the process advances to step S26, and step S2
In step 5, it is determined whether or not the print data file written in the magnetic disk device 13 is to be output, and if it is not to be output, the process is terminated.

When it is determined in step 526 that the print data file is to be output, the process advances to step S27, and step S2
The contents of the print data file saved in step 5 are read out and transferred to the input buffer 11.

Next, in step 528, the contents of the input buffer 11 are analyzed and the image is expanded into the output buffer 14. In step S29, the contents of the output buffer 14 are transferred to the output unit 1.
If it is determined in step 530 that the print data still remains in the print data file, the process returns to step 527 and steps S27 to 530 are repeated.

In the above-described embodiment, the print data sent from the post computer 12 is once saved on the magnetic disk, and then modified using an editing command, and the modified print data is output. The sent print data may be directly displayed for each unit price on the CRT 5, and at this point, the keyboard 7 may be used to make corrections and output.

Also, if you provide a means to specify the page to be corrected at this time,
