Library /sys$common/syshlp/lse$clihelp.hlb GOTO, LINE, Qualifiers, /BOUND  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Moves the cursor to the beginning or the end of the current
    line depending on whether the direction specified is FORWARD or
    REVERSE. If the cursor is already at the specified destination,
    LSE issues a message to that effect and the cursor does not move.
    The /BEGINNING, /BREAK, /BOUND, and /END qualifiers are mutually
    exclusive.
