Functions for Inserting and Appending Lines

Zeile einfügen

Insert Line

The Insert Lines function allows the user to insert a blank line into a table structure and to enter a new element.

Procedure

Move the cursor to the entry before which you want to insert a new line.

Choose the function Insert Lines.

A message in the status bar requests the user to insert data.

A blank line is inserted above the cursor position.

Enter the data and then press ENTER .

The system inserts the data into the table structure and displays the present page of the table structure.

If the user does not enter any data, the blank line disappears. If the user enters incorrect data, the system executes an error procedure.

1 2 3 4 --Fx--> 1 2 _ 3 -- > 1 2 9 3 -- ENTER --> 1 2 9 3

Inserting With a Dialog Box

Alternatively, the entry can occur in a dialog box. If the dialog box is too small to accommodate all of the user's data, it can be enlarged up to full screen size.

Inserting Several Lines

To insert several lines, the user can choose the Insert Lines function repeatedly. The following functions are, however, more efficient.

Insert Many

The function Insert Many allows to create several new elements anywhere in the table structure. The present screen page is expanded accordingly.

Procedure

Der Benutzer stellt den Cursor auf den Eintrag, vor den neue Einträge eingefügt werden sollen.

Choose the function Insert Many.

The table structure is expanded above the selected element. This means, that the line before the cursor position is displayed as the top line of the page while the line on which the cursor was positioned is displayed as the bottom line of the page.

Between the top and bottom lines, the system displays blank lines where the user can enter new data.

The further processing is similar to the processing of the Insert Lines function, with the following difference:
If further data is to be entered after entering the new data, then instead of the ENTER key, the function Insert Many can be called again. As a result, another input screen is displayed: The last line of the already entered data is at the top, and the last line of the preceding insert action is again at the bottom.

After pressing ENTER , the empty lines disappear again.

1 2 3 4 --Fx--> 2 _ _ 3 --> 2 9 _ 3 -- ENTER --> 2 9 3 4

1 2 3 4 --Fx--> 2 _ _ 3 --> 2 9 _ 3 --Fx--> 9 _ _ 3 --> 9 7 6 3

New Lines

With Release 4.0, the meaning and usage of the New entries function has changed. Consider these changes for your new developments.

If, for a table, you assume that the user wants to enter data (independent of the cursor position), display the table with additional input-enabled lines.

If, for authorization reasons, you must check whether the user is allowed only to change the table, execute this check as soon as the user enters the application, if possible. In this case, display the table without additional input-enabled lines. If the user is authorized to both change and create the table, present the table with additional input-enabled lines.

Only if this is not possible, you may return to the old version, using the New entries function (see below).

The function New Lines allows you to create several new elements at the end of a table structure. The word "Lines" can be replaced by a more appropriate term, depending on the task. In contrast to the function Insert Many, this function does not involve cursor positioning.

Procedure

Choose the function New Lines.
The last line of the table structure is displayed at the top of an empty screen page.

To get to the empty screen page, the user should choose a function and not use the Scroll function.

A message in the status bar requests the user to enter data now.

Enter data and then press ENTER

Table structures which are not sorted by field: The new lines are appended to the end of the table structure.

Table structures which are sorted by field: The new lines are sorted into the table structure.

Display after appending:

Table structures which are not sorted by field: The table structure is displayed from the last line before the action.

Table structures which are sorted by field: The table structure is displayed from the first element inserted.

After pressing ENTER , the empty lines disappear again.

Unsorted

1 2 3 4 --Fx--> 4 _ _ _ --> 3 8 5 _ -- ENTER --> 3 8 5 _
