A predetermined address of the buffer area 17a indicated by Ill is read out, and since a code indicating that no character code exists is stored, it is determined that no input data exists in the field F2. The screen input/output control unit 2 is
Data "01" indicating that no data exists in the input/output field is generated, and the main index area of the third control table 10 is searched using this data "01" and the cursor group data "01" as search data. As a result of the search, the screen input/output control unit 4 selects the address r120 of the control table 10.
The data in the control data area of J is read out, and the read data r030J rOJ and r040J rOJ are passed to the field input/output unit 11. This data ro30J
From rOJ, r040J "0", when the field input/output unit 11 receives processing of sequence numbers r030J, r040J, sequence numbers r030J, r04
A clearing and skipping process for a predetermined address in the buffer area 17a indicated by 0J is executed.

When the sequence with sequence number r020J ends,
The screen input/output control unit 4 executes the sequence with sequence number r030J. In executing the sequence of sequence number r030J, the screen input/output control unit 4 first inputs data "030" in the sequence number area, data [EKI080PJ] in the item ID area, data "1" in the G-IX area,
The data "3" in the screen field number area and the data rlJ in the input/output classification area are input to the field input/output section 11 (4).

Here, since the data in the passed sequence number area is data r030J, the field input/output unit 11
Data rEK l 080PJ clears and skips a predetermined address of the buffer area 17a indicated by data "10".

When the processing of the field input/output section 11 is completed, the screen input/output control section 4 next inputs the data rTK of the individual check item area.
OIJ and correlation check item area data rRL O
2J is passed to the data check section 12. When the data rTKO1j and rRL 02J are passed from the screen person output control unit 4, the data check unit 12 outputs the data rEKI080PJ.
"TKol" and rRLO for the data stored at a predetermined address in the buffer area 17a indicated by rlJ.
Perform the data check indicated by 2J. However, since the address is cleared here, the data check section 12
ends the process without performing a data check.

When the sequence with sequence number ro30J ends,
The screen input/output control unit 4 executes the sequence with sequence number r040J. The sequence with sequence number r040J is also processed in the same way as the sequence with sequence number r030J.

When the sequence with sequence number r040J ends,
The screen person output control unit 4 executes the sequence with sequence number [050J.

Note that when the data in the partitioned area is rlJ, the buffer area 1 indicated by sequence numbers ro30J and r040J
7a, the sequence numbers r030J, r
Data is input in the same manner as the sequence 040J.

In the sequence execution of sequence number ro 50J, the screen input/output control unit 4 first inputs data r050J in the sequence number area and data rRETOO3U in the item ID area.
J, data “1” in the G-IX area, data “5” in the screen field number area, data rlJ in the input/output classification area
is passed to the field input/output unit 11. When a character code is input from the keyboard 16b, the field input/output section 11 stores this character code at a predetermined address indicated by rRETOO3UJ rlJ in the buffer area 17a. When the processing of the field input/output unit 11 is completed, the screen input/output control unit 4 then passes the data [TVOIJ, rR303] of the individual check item area to the data check unit 12. Data rTVOI from screen person output control unit 4
When J, rRsO3-1 is passed, data check section 1
2 is rRETOO3UJ rl in the buffer area 17a
A data check indicated by rTVOIJ is performed on the character code stored at a predetermined address indicated by J.

When the processing of the data check section 12 is completed, the screen input/output control section 4 checks the data rL3C6P of the processing request definition area.
Pass J to the custom function section 7. The custom function unit 7 is a function module created by the user, and executes the fE ffi function according to the user's definition.

As described above, the control data of each functional module regarding intra-screen transition is defined in the second and third control tables,
In accordance with the input/output of data, the screen output control section 4 reads out this control data and controls each functional module, thereby easily performing on-screen control.

Each preset standard module section is the minimum necessary functional module to run this system, but the main control section 3 and screen input/output control section 4
By allowing the user to control the plurality of custom module units 7 and 15, it becomes possible to add as many functions as the user desires, thereby making the system more versatile.

[Effects of the Invention] According to the present invention, the selection control of each functional module can be separated from the execution control of each function module itself, so the logic in system construction is orderly and errors in the logic regarding each function are reduced. Furthermore, when a predetermined location does not function correctly, it becomes clear whether the cause is due to the selection control of the functional module or the functional module itself. In addition, each functional module is linked in advance, and the system execution procedure can be changed simply by changing the definition of the control table, eliminating the need for inspection after linking the functional module, making it easier to change specifications, etc. .

The above improves the productivity and quality of software in system construction.
