Discover that there is and click "item 3" with the mouse). Step display means 11
1 indicates a subroutine or input description that uses the set output data item, and if another data item is transferred to the data item, a subroutine or input description that uses the other data item. , If another data item is transferred to the data item using the conditional statement, the source library 102 is searched for a subroutine or input description that uses the data item used in the conditional statement ( (Step 208), all are displayed on the step display screen of FIG. 8 (step 209). Further, the step display means 111 notifies the user of the step including the set output data item and another data item transcribed to the output data item by a "***" mark.

In the case of an error in which the position of the output data item is different from the position in the specifications, when "output data item position error" is selected on the error type selection screen, the search information setting means 110 causes the search information setting means 110 to set the search information shown in FIG. Display the screen. Here, the output data item having the position error can be set by clicking the output data item having the position error in the execution result with the mouse (in the case of FIG. 6, the error occurs in the third line of item 3). Discover that there is and click "item 3" with the mouse). The step display means 111 is a subroutine that uses a set output data item, a subroutine that uses another data item such as an input description when another data item is transcribed to the data item, or a subroutine that uses the other data item. When another data item is transferred to the data item by using a conditional statement such as an input description, a subroutine or input description that uses the data item used in the conditional statement is input from the source library 102. A search is performed (step 208), and all are displayed on the step display screen of FIG. 8 (step 209). Further, the step display means 111 notifies the user of the step including the set output data item and another data item transcribed to the output data item by a "***" mark.

When the line feed position is an error different from the line feed position in the specification, when the "line feed position error" is selected on the error type selection screen, the search information setting means 110 is selected.
Displays the search information setting screen of FIG. Here, for example, if the output data item value is not changed even though the paragraph is specified to be printed by changing the output data item value, but it is printed in another paragraph, execute By clicking the output data item in the result with the mouse, it is possible to set the output data item in which the line feed position error has occurred (in the case of FIG. 7, it was found that there is an error in the line feed process based on the value of item 3). Click "Item 3" with the mouse). Step display means 11
First, the source library 102 is searched for a subroutine or the like that performs line feed processing based on the value of the output data item (step 208) and displayed on the step display screen of FIG. 8 (step 209). Further step display means 1
11 notifies the user of the step including the set output data item with a "***" mark.

If more detailed information exists in the search result, the user can request the display of the detailed information from the step display screen (step 211). For example, when the detailed information display means 112 is selected by inputting a data item name in the item name input field by clicking an arbitrary data item on the step display screen of FIG. Detailed information such as the data type and the number of digits of the selected data item is displayed on the detailed information display screen of FIG. 9 (step 212).

On the other hand, if no error is found in the normal end screen of FIG. 3 or if you want to end each screen,
