       /PROMPTING=prompt-option

    Specifies the level of prompting to be used during the terminal
    session.

    By default, the Edit/FDL utility chooses either BRIEF or FULL,
    depending on the terminal type and the line speed. High-speed
    CRT terminals are set to FULL; nonscope terminals and terminals
    operating at less than 2400 baud are set to BRIEF.

    Example

  $ EDIT/FDL/PROMPTING=BRIEF TEMP_DATA

    This command begins an interactive session in which the value of
    the prompting level for the the Edit/FDL utility menus is set to
    BRIEF.
