-- Command: volumelist ID/K, COMMAND/K, PORT/K, HELP/K, NODE/K,
          ATTRS/K/M
     volumelist objects are created with this command.

        * ID [I..] - an id can be assigned to a volumelist for later
          reference. The id can be any combination of up to 5
          characters.  If the id is given without any other arguments,
          and the volumelist has been previously created, then the
          currently selected volume will be returned in RESULT (if
          OPTIONS RESULTS is specified in the script).

        * COMMAND [I..] - if given, the command will be executed
          whenever an item in the volumelist is double clicked.  For a
          complete description of this option see Command-Port Options.
           Note that the selected volume name will be used to replace a
          `%s' contained in the command string.

        * PORT [I..] - a specific host port may be specified by this
          argument. For a complete description of this option see
          Command-Port Options.

        * HELP [I..] - with this argument help text may be defined
          which will be displayed as balloon help whenever the pointer
          is over the associated volumelist. Of course, this is
          dependant on whether the user set up balloon help in the MUI
          preference settings.

        * NODE [I..] - this argument is used to specify a node in the
          guide file given in the command line argument HELP for
          `MUIRexx'.  If the user positions the mouse pointer over the
          volumelist and presses the help button on the keyboard then
          the guide file will be displayed at the node location.

        * ATTRS [ISG] - with this option any MUIA attribute TAGs may be
          set or retrieved (see Attribute TAGs).

     Some useful TAGs for use with this command are:

          TAG_Name =                        TAG_id          Flags Type
