### Editing an Existing Subroutine

To edit an existing subroutine you can always use the Edit window's Command mode and edit the subroutine directly. Alternately, you can access the Subroutine Creation dialog box by placing your cursor on the subroutine in the Edit window and pressing F9. This brings up the Subroutine Creation dialog box. For information on this dialog box, see the "Understanding the Subroutine Creation Dialog Box" topic.
