Abstract

PURPOSE:To output only a desired data by operating once, by providing a means for storing a data group, a data designating means, a data reading means, a means for discriminating a designated data, and a means for outputting a data, based on a result of discrimination. CONSTITUTION:From a keyboard 7, an output object range in a magnetic tape, and a group number of a data file number whose output is unnecessary, in the range are inputted, and stored successively in an instruction control table 4a. Subsequently, a data is inputted into a group in order of the time series to a buffer 8 from a tape 9, and when it is decided that the data is a data designated in the table 4a, the end of a processing is confirmed. When it is decided that a data file in the table 4a and a read data do not coincide, the read data is developed in a buffer 5 and printed. When it is repeated to the last, a data in an intended file is printed. According to this constitution, by designating an unnecessary data, only a desired data can be printed, and a key input from the keyboard is decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device, and particularly to an information processing device that reads and outputs data from a storage device that stores a plurality of data.

[Prior Art] In conventional devices of this kind, especially general-purpose computers, when outputting a desired data file stored on a magnetic tape to a display device or a printing device, the output start position of a series of data files is determined. Specify and end position and press C again.

[Problems to be Solved by the Invention] However, if this output range is specified and displayed or printed, all data within that range will be output.

For example, if necessary data files are stored on a magnetic tape at random, there is a problem in that even unnecessary data files become output targets.

Therefore, it is conceivable to perform the above-mentioned operations on each data file and output them, but this would be troublesome and the work efficiency would be extremely poor.

The present invention has been made in view of such prior art, and it is an object of the present invention to provide an information processing device that makes it possible to output only desired data in a single operation.

[Means for Solving the Problem] As one means for solving this problem, the present invention has the configuration shown below.

That is, a storage means for storing a plurality of data groups, a designation means for designating at least one of the data, a reading means for reading the data stored in the storage means, and the read data is stored in the designation means. and an output means for outputting the read data based on the determination result of the determining means.

[Operation] The data stored in the storage means is sequentially read by the reading means, and the determining means determines whether the read data matches the data specified by the specifying means. The output means outputs the result based on the determination result of the determination means.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of the configuration of an information processing apparatus in this embodiment.

In the figure, 1 is a CPU that controls the entire information processing device,
2 is a bus that controls the exchange of various data. 3 is CPUI
This ROM stores an operating program, and also stores a program shown in the flowchart of FIG. 4, which will be described later. 4 is a RAM used as a work area during processing operations of the CPUI, and a command control table 4a for controlling command execution is provided therein. The contents of this command control table 4a will be described later. Reference numeral 5 represents an output buffer memory for rasterizing data to be output to the printer 6, and reference numeral 7 represents a keyboard for inputting designation information for various operations. Reference numeral 8 denotes an input buffer memory that temporarily stores data read from the magnetic tape device 9. The data format in the magnetic tape stored in this magnetic tape device 9 is as shown in FIG. positioned.

Now, in the configuration described above, when an operator instructs to output a group in a data file that he/she needs, he/she specifies the range and also outputs a data file that is not needed.
, the group Jln inside can be specified using the keyboard 7. In other words, the specified group is skipped (ignored).
It reads and prints out only the data files that are needed. Incidentally, the files and groups specified using this keyboard 7 are sequentially stored in the command control table 4a as shown in FIG.

Therefore, when reading a data file from the magnetic tape device 9, the CPtJl checks the information in the command control table 4a, skips reading for files that match, and sequentially expands unmatched files into the manual buffer 8. . The CPU 2 develops the information developed in the manual buffer 8 into the output buffer 5 and prints it out.

A summary of the above processing will be explained according to the flowchart of FIG.

First, the operator inputs from the keyboard 7 the range to be output on the magnetic tape and the group number of data file numbers within that range that do not need to be output. In step S2, this input data is sequentially stored in the command control table 4a.

Now, when this manual processing is completed, the process moves to step S3, and the data is inputted into the input buffer 8 from the magnetic tape into the groups in chronological order, but in the next step S4,
If it is determined that the data is the data specified in the command control table 4a, the process moves to step S6 without being expanded onto the output buffer 5. In step S6, it is determined whether the process has ended, that is, whether the input data is the last data specified in the range. If this judgment is "No'", the process returns to step s3.

On the other hand, in the judgment in step S4, the command control table 4
If it is determined that the data file stored in a does not match the data read from the magnetic tape,
Proceeding to step S5, the read data is developed on the output buffer 5 and printed out.

If the above-described process is repeated until the end, the data in the file intended by the operator will be printed out.

As described above, according to this embodiment, by specifying unnecessary data, it is possible to print out only desired data.

In this embodiment, the designated data is skipped (ignored), but the designated data may be outputted with the mark 111.

In particular, it is possible to switch between skipping and printing specified data based on the ratio of necessary data to unnecessary data in the data group recorded on the magnetic tape, which saves manual effort from the keyboard. It is possible to reduce it.

Furthermore, although this embodiment deals with an offline system that uses a magnetic tape device as a human-powered device,
Offline data supplied from the host computer
It doesn't matter whether it is a system, or even if a series of data groups has a structure that allows not only two levels of files and groups as shown in Figure 3, but also a structure that allows detailed group specification below that information. It is possible to perform the same processing simply by registering in the command control table 4a the same way as in this embodiment.

[Effects of the Invention] As explained above, according to the present invention, it is possible to output a data group intended by the operator with a simple operation.
