The message definition body 4a holds the format for displaying data items on the display device 1a (item name, item display position, display attributes, etc.) and the position in the record area where input data is stored.

The message editing program 5a is a message definition body 4
A screen is displayed based on the specification of a, and the data input by the user is edited into a predetermined format according to the display screen and input into the user program 3a.

Therefore, based on the screen displayed on the display device 1a according to the specifications of the message definition body 4a, the user can select the fields corresponding to each item (Fig.
), and the input data is stored in a record area (not shown) according to the specifications of the message definition program 4a, and the input data is stored in the record area (not shown) in the user program 3 a l';! It is configured to perform processing based on this data.

Here, the message fixing body 4a is created in advance by a definition body creation tool (not shown) (a program that supports creation of the message definition body 4a), and conventionally, the position t1 in the record area of the data item is a field on the screen. The data items corresponding to the data items were defined in the record area so that they were arranged in ascending order of the lines on the screen. That is, the data items defined on the screen as shown in figure (bl) are displayed in the record area as shown in figure (C1).
They were arranged in the order of ■;■, ■;■, ■.

[Problem to be solved by the invention]

As described above, according to the conventional method, there is a one-to-one correspondence between the position of a data item on both sides and the arrangement order in the record area, so when the processing order of the user program and the arrangement order of stored data items differ, It is necessary to re-edit the data array in the record area, such as when placing data items that are not required to be sent to the host computer at the end of the permutation.
There was a problem in that it placed a large load on the user program.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data item rearrangement method that can easily change the order in which data items on a screen are arranged in a record area.

[Means to solve the problem]

FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, 4 stores information specifying the display format of data items including the display position on the display device 1, and the data of the items input from the input device 2 based on the displayed screen and sends it to the user program. a message definition section 5 that stores information 41 specifying a position within the area to be transmitted; 5 a message control section that displays data items and stores data of input items based on the specifications of the message definition section 4; , 6 is means for inputting a command to change the storage position information 41, 7 is a means for inputting a command to change the storage position information 41, and 7 is a means for inputting a command to change the storage position information 4.
