Default: False         Value: True or false

    Specifies whether Session Control should attempt to update
    the backward translation soft links when it detects an address
    change. If this attribute is set to false, Session Control will
    add no new backward translation soft links and it may delete any
    that it has created.

    On OpenVMS, even though the default NCL value for this attribute
    is False, the sys$manager:net$session_startup.ncl script resets
    this attribute to True.

    Examples:

    set session control maintain backward soft links true

    set session control -               ! Resets the attribute to
          maintain backward soft links  !  the default, which is
                                        !  False.
