You can create or modify generation elements related to
the database or the description lines of a Block, depending on whether
the -GG Lines subtab is one of the Block description
line tab (-DR Lines, -DH Lines or -DC
Lines, according to the Block type) or one of the Database
Block editor -GG Lines tab.
About this task
The definition and description lines of a Database Block
provide all the logical information needed to generate the source
program of the Block. The physical information must be indicated on
the -GG lines associated with the definition of a Block and on the
-GG lines associated with a description line to modify it. You can
modify or create generation lines in the following table. This table
is available in the
-GG Lines from the
-G
Lines tab of a Database Block editor, or from the
-DH
Lines, or
-DR Lines or
-DC
Lines tab of a Database Block:

lines section in the -DR lines tab of a Block 
Lines identified
by the 'VIRT' and 'GUID' notation in the From field
of the table correspond to virtual lines which are automatically generated
and cannot be modified. You must create other lines from these lines
to add modifications to the generation data so that they are recognized
upon generation.
Procedure
Possible actions on the generation lines:- To create a line, click Add .
In the Type field, click and select, in the
drop-down list that is automatically displayed, G for
a generation line, V for a virtual line, or * for
a comment to be generated. The lines created in this way are then
identified by their type. These lines can be modified. Overriding
virtual lines will not impact source lines but the lines will be copied
into the target instance.
- To modify VIRT and GUID lines, you must override them.
To do so, click a line to be overridden, then click the Override button.
The line is edited, you can modify its description and type. Moreover,
the GUID notation turns into FromGUID and the GUID notation turns
into FromVIRT.
- You can then modify the lines with a FromVIRT or FromGUID
notation. You must select the line you want to modify and click F2
to edit it. Then you can change its type or description.
- You can remove, move up ↑ and
down ↓ only the comment lines, the FromGUID
and FromVIRT lines and the lines you have added to the table. To do
so, use the buttons on the right side of the table.
- You can use the Undo, Redo, Copy, Paste, Revert, Delete
options in the pop-up menu (right-click) for any edited line.
