       /DIALOG
       /NODIALOG (D)

    Instructs LSE to use a dialog box to prompt the user for
    parameters and qualifier values. The command parameters are
    optional if you specify this qualifier. If you supply command
    parameters and qualifiers with the /DIALOG qualifier, these
    parameters and qualifiers are used to set the initial state of
    the dialog box.

    LSE ignores the /DIALOG qualifier if you are using a character-
    cell terminal.
