Appends a new row in the specified list.

The appendRow() method appends a row to the end of the array controlled by the dialog.

Important: This method is designed to be used in an ON ACTION block. It must not be called in control blocks such as BEFORE ROW, AFTER ROW, BEFORE INSERT, AFTER INSERT, BEFORE DELETE, or AFTER DELETE.

The method is similar to appending a new element to the program array, except the internal dialog registers are automatically updated (like the total number of rows returned by getArrayLength()). If the list is decorated with cell attributes, the program array defining the attributes will also be synchronized. If multi-row selection is enabled, selection flags of existing rows are kept. The new row is inserted at the end of the list with the selection flag set to zero.

Note: The purpose of this method is to implement business logic required to modify the record list in the current dialog. It is typically used in a DISPLAY ARRAY dialog. Avoid using this method in INPUT ARRAY. To allow the end user to append, modify or delete rows in a DISPLAY ARRAY, use list modification interaction blocks.

After the method is called, a new row is created in the program array. You can assign values to the variables before the control goes back to the user. The getArrayLength() method will return the new row count.

The method does not set the current row and does not give the focus to the list; you need to call setCurrentRow() and execute NEXT FIELD to give the focus.

This method does not execute any BEFORE ROW, BEFORE INSERT, AFTER INSERT or AFTER ROW control blocks.

The appendRow() method does not create a temporary row as the implicit append action of INPUT ARRAY; the row is considered permanent once it is added.


This example implements a user-defined action to append ten rows at the end of the list.
ON ACTION append_some_rows 
  FOR i = 1 TO 10
    CALL DIALOG.appendRow("sa")
    LET r = DIALOG.getArrayLength("sa")
    LET p_items[r].item_quantity = 1.00
