/ATOMS=file-specification

    Specifies the file that the proxy server should use for atoms
    control. The file SYS$MANAGER:DECW$ATOMCONTROL.TEMPLATE contains
    an example of an atom control file. This qualifier cannot be
    specified if the NOATOMS or NOLBX option is specified for the
    /OPTIONS qualifier.

    The default is /ATOMS=SYS$MANAGER:DECW$ATOMCONTROL.DAT.
    However, effectively the default is not to use atom
    control, because the installation process does not convert
    the SYS$MANAGER:DECW$ATOMCONTROL.TEMPLATE file to the
    SYS$MANAGER:DECW$ATOMCONTROL.DAT file.

    At startup, the LBX proxy server "pre-interns" the atoms
    specified in the atom control file. The atom control file also
    controls when the proxy server should delay sending data to the X
    server. This is done by specifying the following:

    o  Minimum data length required before the server delays any
       data.

    o  Which atoms should be delayed only when a window manager is
       running on the same connection.

    The format of the atom control file is documented in the
    SYS$MANAGER:DECW$ATOMCONTROL.TEMPLATE file.
