Creating and modifying the -GG lines of a Database Block

You can create or modify generation elements that are related to the database on the Database Block editor -GG Lines tab. You can also complete the description lines of a Block and enter generation elements on the -GG lines that are associated with the description lines. To do so, click the -G Lines button that is available on the description line definition in the -DR Lines, -DH Lines or -DC Lines tab, according to the Block type.

About this task

The definition and description lines of a Database Block provide all the physical information that is required to generate the source program of the Block.
The physical information must be indicated on the -GG lines at two levels:
  • The Block definition,
  • The -DH, -DR or -DC description lines, according to the Block type.

You can modify or create these generation elements.

The lines that are identified by VIRT and GUID in the From column correspond to virtual lines. They are generated automatically. They guide you when you enter your generation elements. They cannot be modified directly. You must create other lines from these lines to insert modifications that will be recognized upon generation.

Procedure

The following actions are possible on the -GG Lines of a Database Block:
