DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device.

[0002]

2. Description of the Related Art File organization refers to the arrangement of records on devices and storage media handled by file management. For example, the indexed sequential organization of the file organization defines one item in a record as a key so that it is easy to access the order of the keys or to access the record with the desired key. A file organization with an index structure. In some cases, data conversion processing is performed in which data processed by an office computer or the like is converted into an external storage device such as an MT or FD and registered. In this case, the data conversion process needs to be changed depending on whether the registration target is the FD or the MT.

[0003]

Therefore, when there is no designated device (external storage device) at the time of data conversion execution or when information of the designated device is different, data conversion processing cannot be executed, and after the output device conversion, the data conversion process is not performed again. There is a problem that the information has to be executed, the information must be redefined from the beginning, or maintenance must be performed and then executed again. In addition, there is a problem that when data is not stored in the FD or the like, the data cannot be stored, the multi-volume operation is performed, and even when there is no FD to be exchanged, the process must be stopped and executed again. Further, when registering data in different external storage devices, there is a disadvantage that the same data conversion process must be performed a plurality of times. Thus, it is clear that if only the data conversion process is executed even when there is no target device to be used when executing the data conversion, it is not necessary to re-execute the data conversion process.

An object of the present invention is to ensure that data to be output can be held even when all data cannot be output to a designated device.

[0005]

According to the present invention, there is provided a designating means for designating an output device for outputting data, and a judging means for judging whether or not the data can be outputted to the output device designated by the designating means. Registering means for registering the data in a temporary file together with device information indicating the specified device when the determining means determines that the data cannot be output to the designated device; and storing the device information registered in the temporary file. Control means for reading out the data registered in the temporary file and outputting the data to the designated device represented by the device information,
It is characterized by having. Therefore, even when data cannot be output to the designated device, the data to be output can be reliably held. [Description of Functional Block Diagram] FIG. 1 is a functional block diagram of the present invention. In the figure, 1 is a data processing means, 2 is a designation means, 3 is a registration means, and 4 is an output means.

An embodiment will be described below with reference to FIGS. 2 to 7 are diagrams showing an embodiment of the data processing device. First, the configuration will be described. FIG. 2 shows a data processing device 1
0 is a block diagram of FIG. In FIG. 1, reference numeral 11 denotes a CPU which controls the entire apparatus, and performs various data processing including a data conversion process and a temporary file reading process described later.
The CPU 11 controls various operations of the data processing device according to a microprogram stored in a ROM (not shown). The CPU 11 includes an input file 12 that stores input data to be converted, a data conversion device 13 that reads data from the input file 12 for each field and converts the data, and a conversion data that is converted by the data conversion device 12. Is not registered in the specified external storage device (device), a temporary file 14 for temporarily registering the data, and device information of the conversion data registered in the temporary file 14 (which device is connected and registered External device (including a device information memory 15 for storing information indicating whether the data should be converted), a floppy disk (FD) 16, a magnetic tape (MT) 17, and the like for registering and storing converted data after data conversion. Designated device) 18 and a keyboard equipped with keys for inputting various data and function keys, etc. Input unit 19, the input data, and a display unit 20 for displaying processing data and the like are connected that.

FIG. 3 shows the structure of the temporary file 14. In this figure, a temporary file 14 is constituted by, for example, a large-capacity fixed disk.
Is stored as block data 31 to 33 in a form in which device information 21 to 23 of data conversion and corresponding data subjected to data conversion I to III are converted. Further, when a multi-volume is obtained by the data conversion processing described later, a multi-volume is also set in the temporary file 14 as shown in FIG.

Next, the operation of this embodiment will be described. FIGS. 4 and 5 are flowcharts showing a data conversion process for converting data stored in the input file 12 and registering the data in the temporary file 14. In FIG. 4 and FIG.
= 1, 2,...) Indicate each step of the flow.

When the program starts, it is first determined at step S1 whether or not there is a device designation for data conversion.
In step 2, it is determined whether the device matches the currently designated device.
If the device matches the currently specified device, a flag is set in step S3 and the process proceeds to step S5. If the device does not match, the device information is set in the temporary file 14 in step S4 as shown in FIG. . If there is no device designation in step S1, the process simply proceeds to step S5 because writing to the temporary file 14 is unconditional and device information is not required. That is, when there is no device designation, a certain data conversion is performed and the result is stored in the temporary file 14. This corresponds to a case where the content of the temporary file 14 is later designated and stored by specifying a device. In this way, if there is no relation between the devices trying to match, the device is not designated as shown in FIG. If the device is not specified, the flag set (step S3) described later has not been made, so that the data of the temporary file is written in step S9 and the process returns to step S5. Will be written to.

In step S5, one record is read from the input file 12 to be converted. In step S6, it is determined whether or not the record has been completed. If all records have been completed, the processing of this flow is completed. In step S7, data read by the data conversion device 13 is subjected to data conversion processing for each field. Next, in step S8, it is determined whether or not the flag is set. If the flag is not set (when there is no device designation or when the devices do not match), step S8 is performed.
In step 9, data is written to the temporary file 14, and the process returns to step S5. If the flag is set, the data of the currently designated device is written in step S10 (for example, as shown in FIG.
Then, it is checked whether or not the data is over in step S11. If the data is not over, the process returns to step S5 to repeat the above-mentioned processing. If the data is over, a temporary file or a device is designated in step S12. For example, when FDD (floppy disk drive) is designated as the designated device and the data writing exceeds the capacity of the device (FD), the operator operates the keys at that time and stores the subsequent data in the temporary file 14. It is designed to specify whether to write or to exchange the device again and directly to the FD. In other words, when the data is over when there is only one FD, the data that becomes data over must be written to the temporary file 14, but when there is two or more FDs as shown in FIG. Specifies whether the temporary file is a device again (step S1).
2). If the temporary file 14 is specified in step S13 by the specification (for example, when there is only one FD), the device information is set in the temporary file 14 as shown in FIG. The volume is set in the temporary file 14, the flag is reset in step S16, and the process returns to step S5.
When the temporary file 14 is not specified (for example, when there are two FDs), the multi-volume is set in the device in step S17, and the process returns to step S5 to repeat the above processing.

FIG. 7 is a flowchart showing a temporary file reading process when reading data registered in the temporary file 14 and registering the data in the external storage device (device) 18. First, in step S21, it is determined whether there are a plurality of blocks of data in the temporary file 14. Here, whether or not there are a plurality of blocks is determined based on the fact that the temporary file 14 is divided by the device information 21 to 23 as shown in FIG. If not separated, one block is used instead of a plurality of blocks. If there is no plurality of blocks, it is determined in step S22 whether or not there is device information. If there is no device information, in step S23, a device is specified by key operation. If there is device information, the process proceeds to step S27. Next, in step S24, it is determined whether or not the data matches the currently specified device (the currently connected device). If the data matches the currently specified device, the block data is transferred to the currently specified device in step S25. When the data is written out and the processing of this flow is completed, and the device does not match the currently specified device, the process jumps to step S25 and ends. That is,
If one block does not match the specified device, the process ends here.

On the other hand, if there are a plurality of blocks in the step S21, the device information of the first block shown in FIG. 3 is read out in a step S26, and it is determined in a step S27 whether or not it matches the currently specified device. The block data of the currently specified device (block data 31 in FIG. 3)
33), and the block data is deleted from the temporary file 14 in step S29, and the process proceeds to step S30.
If it does not match the currently specified device, steps S28 and S29 are jumped to step S30. Thus, the reading of the temporary file in a certain data conversion (for example, the data conversion I in FIG. 3) ends.
Next, in step S30, the next block data is specified. In step S31, it is determined whether or not there is a block. If there is a block, the device information of the next block is read in step S32, and the process returns to step S27. Is read out and the above processing is repeated. Then, when all blocks are exhausted in step S31, the processing of this flow is finished.

As described above, the data processing apparatus 10 of this embodiment includes a CPU 11, an input file 12 for storing input data to be converted, and a data conversion by reading data from the input file 12 for each field. A data conversion device 13, a temporary file 14 for temporarily registering the converted data converted by the data conversion device 12 when the converted data cannot be registered in the specified external storage device 18, and a temporary file 14 for temporarily registering the data. A connection device information memory 15 is provided for storing device information of the conversion data to be registered (information indicating which device is to be connected and to be registered). In the data conversion processing, if the specified devices do not match, the connection is registered in the temporary file 14 In advance, it is possible to output to the specified device later, so when performing data conversion, Regardless of the external storage device 18 to be output, data conversion processing is executed and registered in the external storage device 18 later, and there is no designated device (external storage device) at the time of data conversion execution. In such a case, it is possible to eliminate the trouble of stopping the process and executing the process again after the output device is changed. In addition, since the converted data is registered in the temporary file 14, a plurality of devices other than the designated device can be registered. Furthermore, in the case of the external storage device 18 such as the FD 16, by registering the remaining data in the temporary file 14 when there is no FD to be exchanged at the time of multi volume,
It is possible to save the trouble of executing the first registration.

In this embodiment, an example in which the processing result of the data conversion processing is registered in the external storage device 18 has been described. However, any method may be used as long as the processing result is output to the designated device. The present invention is not limited to this, and can be applied to a case where the processing result is transferred to an external device by communication.

Further, in the present embodiment, an example in which data conversion processing is performed as an example of data processing has been described. However, the present invention is not limited to this, and any processing that performs data processing may be used.

[0017]

According to the present invention, when data cannot be output to a specified device, the data is registered in a temporary file together with device information indicating the specified device, and the data registered in the temporary file is read and output to the specified device. In this case, the device information registered in the temporary file is read out, and the data registered in the temporary file is output to the designated device represented by the device information. Therefore, the data to be output is securely held, and the designated device is prepared. At this point, the temporary file data can be output to the specified device.
