In the Line Numbers dialog box, you can create new line numbers and select which lines you do or do not want to use in the standard.

A few things to note about the Lines dialog box:
§ Users will be unable to use or see the line in the standard unless it is checked off.
§ To create a new line, purge, or rename a line, use the buttons at the top of the dialog box.
§ When you purge a line, it will be permanently removed from the database and you will be unable to recover it.
§ In order for the Purge button to be enabled, the line must be unchecked.
