Abstract

PURPOSE:To increase the execution efficiency of a program by using after- conversion input data to be stored in a file from a next time at the time of repeatedly execution the program to input the input data different from the internal data expression of a transplanting destination computer system. CONSTITUTION:An input means inputs option information to contain information to designate whether input data 5 are the data in a second expression format to be processed by a second computer or not and information to designate whether or not to store the data in the second expression format obtained by converting the expression format of the data in a first expression format. A data deciding means 40 decides whether or not to convert the expression format of the input data based on the option information. A data converting means 41 converts the expression format of the input data, prepares the data in the second expression format and outputs them when the fact that a necessity to convert the expression format of the data exists is decided by the data decid ing means 40. A data storage deciding means 43 decides whether or not to the store the data in the second expression format prepared by the data converting means 41 based on the option information. Thus, the execution effi ciency of the program can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an input data conversion method for converting input data of one computer into input data of another computer, each of which has a different internal data representation.

(Prior Art) There are cases where it is desired to port programs and data that were developed for a certain computer system and executed on that computer system to another computer system for execution. During porting, data representations within the computer systems may differ between one computer system (portion destination computer system) and another computer system (portation destination computer system). In such cases, even if the program is repeatedly executed using the same input data on the destination computer system, the data representation of the input data is converted each time the program is executed. . This data representation conversion process generally takes a very long time.

(Problems to be Solved by the Invention) As described above, the conventional data conversion method requires conversion of the data representation of input data each time, even when the same human data is used to repeatedly execute the program on the destination computer system. Processing is in progress. Therefore, the process of converting the data representation of input data, which takes processing time, is performed every time the program is executed, resulting in poor program execution efficiency.There are problems that need to be solved with conventional input data conversion methods. there were.

The present invention has been made in view of these circumstances, and its purpose is to provide an input data conversion method that can improve program execution efficiency.

(Means for Solving the Problems) In order to achieve the above object, the input data conversion method of the present invention converts data expressed in a first expression format handled by a first computer to In an input data conversion method in which data in a second expression format different from the first expression format is generated and used as input data for a second computer, the second expression allows the input data to be processed by the second computer. optional information including information specifying whether or not the data is in the first expression format and information specifying whether or not to save the data in the second expression format that cannot be obtained by converting the expression format of the data in the first expression format. an input means for inputting data; a data determining means for determining whether or not to convert the representation format of the input data based on the option information; a data conversion means for converting the representation format of the input data to generate and output data in a second representation format, and the second representation generated by the data conversion means based on the option information; data storage determination means for determining whether or not to save the data in the second expression format; and when the data storage determination means determines to save the data in the second expression format, the and converted data storage means for storing the second expression format data in a file.

(Operation) In the input data conversion method of the present invention, the input means
Information specifying whether the input data is data in the second expression format that can be processed by the second computer, and data in the second expression format obtained by converting the expression format of the data in the first expression format. The data determining means determines whether or not the representation format of the input data is to be converted based on the option information.

When the data conversion means determines that it is necessary to convert the data representation format by the data determination means,
Converting the representation format of the input data to generate and output data in a second representation format, and the data storage determining means storing the data in the second representation format generated by the data conversion means based on the option information. Determine whether or not to do so.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, 1 is option information, 2 is option analysis means, and 3 is option information.
is option analysis information, 4 is an input mechanism, 5 is input data, 6 is saved data, and 7 is a user area. Input mechanism 4
are data determination means 40 and input data conversion and transfer means 41
, input data transfer means 42, data storage determination means 43, and converted data storage means 44.

Next, the operation of converting the data representation of input data in the embodiment shown in FIG. 1 will be explained. When activated from the outside, the option analysis means 2 operates first. The option analysis means 2 includes information as to whether or not it is necessary to convert the data representation of the input data 5, and whether or not to save the input data after converting the representation of the input data 5 in accordance with the porting destination computer system. Enter save option information, which may include: Then, it analyzes this option information and outputs option analysis information 3 that can be processed by the input n top 4.

Next, the data determining means 40 of the input a structure 4 inputs this optional analysis information 3 and determines whether or not the data representation of the input data 5 needs to be converted. When there is no need to convert the data representation, the input data transfer means 42 is activated. Note that the operation of the input data transfer means 42 will be described later.

On the other hand, when it is necessary to convert the data representation, the input data conversion and transfer means 41 is activated.

The activated input data conversion and transfer means 41 inputs the input data 5, converts it into the data representation of the porting source computer system, and generates converted input data.

Then, this converted input data is stored in the data storage determining means 4.
Pass it to 3 and start this.

The activated data storage determining means 43 determines whether it is necessary to store the converted input data based on the option analysis information 3. When there is no need to save, the converted input data received from the input data conversion and transfer means 41 is stored in the user area 7.On the other hand, when it is necessary to save the converted input data, the converted input data is stored in the user area 7. The data is passed to the converted data storage means 44 and activated.

In response to this, the converted data storage means 44 stores the converted input data in the storage data 6 and also in the user area 7.

Now, as mentioned above, when there is no need to convert the input data representation, the data determination means 40 uses the input data transfer means 4
Start on 2. The activated input data transfer means 42 inputs the input data 5 and stores it in the user area 7.

When executing the same manual data for the second time, the option information specifies that there is no need to perform data expression conversion processing, and the saved data 6 is used as the input data 5. Therefore, from the second time onward, there is no need to convert the data representation of the input data.

(Effects of the Invention) As explained above, the input data conversion method of the present invention is effective when executing a program that inputs input data different from the internal data representation of the porting destination computer system many times. Only the data expression of the input data is converted, the converted input data is saved in a file, and the converted input data saved in this file is used from the next time onwards. Therefore, by adopting the input data conversion method of the present invention, it is no longer necessary to convert the data representation of input data, which takes processing time, every time a program is executed, and the program execution efficiency is increased.
