This command allows you to delete one or more lines from the FDL file. If the line is the only remaining secondary attribute in a primary section, the primary attribute is also removed. After you remove a line, you can optionally continue to delete lines under the affected primary section.

This command allows you to delete lines from your existing FDL file.

After you enter the name of a primary attribute, the Edit/FDL utility prompts you with another menu displaying the current secondary attributes for the selected primary attribute and asks which secondary attribute value you want to change.

This command ends the Edit/FDL utility session. The EXIT command causes the new FDL file to be created. This command is equivalent to pressing Ctrl/Z. If the definition file is empty when you exit, no FDL file is created. Refer to the online help topic Operation for more information on the Edit/FDL utility's relationship to input and output files.
