-G Lines associated with the description lines of a Database Block

In the -G Lines creation wizard, you can enter generation elements on the -GG lines that are associated with a Database Block description line.

You open this wizard from the -D line definition section of the Database Block description tab (-DR Lines, -DC Lines, or -DH Lines). In this wizard, you can add generation elements on -GG Lines. For the -DR lines, you can also enter comments for the selected description line on -GC Lines.

In the -GG Lines tab, you can modify the information that is indicated in the Block description lines before the generation. Lines are automatically displayed to guide you when you enter the physical information of the Block. These lines are identified by VIRT or GUID in the Source column. These lines are called virtual lines. Only the lines that are identified by VIRT are generated.

To modify these lines, you must override them (Override button) and create lines between the beginning and end insertion lines. When you override these lines, the VIRT and GUID identifiers are changed into FROMVIRT and FromGUID. The lines can then be entered.

You can create lines anywhere in the table. To edit a line, select it and press the F2 key.

The table contains the following columns:
Error
This column displays a dot on all the existing description lines that are not empty.

Moreover, if this line is not correct, this column also displays an error or warning symbol, depending on the severity of the error. A hover help indicates the source of the error.

Type
When you click a line in this column, a list is displayed. You must select one of the following values:
  • *: comment lines to be generated,
  • V: lines generated before the automatically generated elements,
  • G: line generated instead of the automatically generated elements,
  • P: lines generated between the automatically generated elements and their descriptions,
  • Z: lines generated after the automatically generated elements.
    Note: P and Z types are available only on the -GG lines that are associated with CODASYL Blocks (Definition and -DC Lines tabs).
Description
This field must be used to enter the generation elements or comments to be generated. Its content depends on the selected Block type and line type.
