-- Command: object ID/K, HELP/K, NODE/K, CLASS/K, BOOPSI/S, ATTRS/K/M
     Objects from MUI internal, external and BOOPSI classes are created
     with this command.  Note that while this is a very powerful and
     flexible command it can easily result in the unexpected, including
     system crashes, so beware.

        * ID [I..] - an id can be assigned to a object for later
          reference. The id can be any combination of up to 5
          characters.

        * HELP [I..] - with this argument help text may be defined
          which will be displayed as balloon help whenever the pointer
          is over the associated object. 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
          object and presses the help button on the keyboard then the
          guide file will be displayed at the node location.

        * CLASS [I..] - this argument allows specification of the
          object class. The class may be any internal or external MUI
          or BOOPSI (see the BOOPSI option) gadget class.

        * BOOPSI [I..] - if this switch is given then the object will be
          created from a BOOPSI gadget class.  BOOPSI objects will, by
          default, have the following TAG ids and values set:

               TAG             value
               
               GA_Left         0
               GA_Top          0
               GA_Width        0
               GA_Height       0
               ICA_TARGET      ICTARGET_IDCMP

        * 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
