One of the most powerful features of Enterprise Analyzer lets you auto-extract screen labels as business names for program variables. For each screen field with a label immediately to its left in the Screen pane, the Glossary tool generates a business name for the program variable whose value is displayed in the field. If the screen field has the label Customer Number, for example, Glossary assigns the business name "Customer Number" to the variable whose value is displayed in the field.
Occasionally, however, you may need a finer-grained approach than the auto-extract feature offers. The field of interest may not be immediately to the right of the label, or the field may have no label at all. In these situations, you can extract business names for program variables manually in the Screen pane.
