Library /sys$common/syshlp/dbg$help.hlb DEBUG, SCROLL, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SCROLL command moves a display up, down, right, or left
    relative to its window so that various parts of the display text
    can be made visible through the window.

    Use the SELECT/SCROLL command to select the target display for
    the SCROLL command (the current scrolling display).

    For a list of the key definitions associated with the SCROLL
    command, type Help Keypad_Definitions_CI. Also, use the SHOW KEY
    command to determine the current key definitions.

    Related command: SELECT.
