The prompt-level of the Edit/FDL utility depends upon whether an
    OpenVMS-supported video terminal is being used or not. If your
    terminal is, in fact, a terminal which is supported by OpenVMS
    systems, verify that the terminal driver supports it using the
    DCL command SET TERMINAL/INQUIRE.

    On foreign, slow baud rate, or hardcopy terminals, the default
    mode of the Edit/FDL utility is BRIEF. On terminals running at a
    speed of 2400 baud or greater which are classified as "Video" by
    the SHOW TERMINAL DCL command, the default mode is FULL.

    Refer to the OpenVMS DCL Dictionary for complete information
    about SHOW TERMINAL and SET TERMINAL.

    The special character "?" can be used to retrieve more
    information (or possibly display a Menu) about any particular
    question.

    The prompt-level of an editing session can be set with the
    /PROMPT qualifier on the DCL EDIT/FDL command.
