       Labelbar has six internal parameters, each of which affects the behavior of LBLBAR in a particular way.
       The current value of one of these parameters may be retrieved by calling either LBGETI or LBGETR and the
       value of one of them may be reset by calling either LBSETI or LBSETR.

       Parameter descriptions, in alphabetical order, of all Labelbar internal parameters follow. Each
       description begins with a line giving the parameter name and the intrinsic FORTRAN type of the parameter.

       'CBL' - Integer
              Color of box lines. The default value is -1.

       'CFL' - Integer
              Color of fill lines. The default value is -1.

       'CLB' - Integer
              Color of labels. The default value is -1.

       'WBL' - Real
              Width of box lines. The default value is 0.

       'WFL' - Real
              Width of fill lines. The default value is 0.

       'WLB' - Real
              Width of label lines. The default value is 0.

       Each  of  the  "color" parameters may be given a negative value to indicate that color is unspecified; in
       this case, the color of an object drawn will be that specified by the current polyline  color  index  (in
       the  case  of  box lines and fill lines) or the current text color index (in the case of labels). A value
       which is zero or greater specifies the color index to be used.

       Each of the "width" parameters may be given a value of zero or  less  to  indicate  that  line  width  is
       unspecified;  in  this  case, the line width used to draw an object will be that specified by the current
       polyline width scale factor.  Note that setting polyline width before  drawing  the  labels  does  affect
       their  appearance;  this  is  because  labels are drawn by calls to the routine PLCHHQ, which strokes out
       characters using lines.
