All bar lines originate at the bottom line of of the staff indicated by p2.

P4 = number of staves upward extension.  If p4 = 3 and p2 = 2, the bar line
     will extend from the bottom line of staff 2 up to the top line of staff 4.
     If p4 = -1 = the bar line will be invisible on hard copy.  Invisible bars
     are sometimes needed in the page layout system.

P5 = 0 = ordinary bar
   = 1 = double bar (two thin bars)
   = 2 = ending double bar (1 thin, 1 thick)
   = 3 = repeat double bar, pointing left (thin, heavy - dots to left)
   = 4 =    "     "     "      "     right (heavy, thin)
   = 5 =    "     "     "      "     both ways (thin, heavy, thin)
   = 6 =    "     "     "      "      "    "   (heavy, heavy)
   = 7 = dashed bar. (P8=size of dash, p9=size of space, default 2,1)
   = 8 = curved brace
   = 9 = heavy bracket (see re. parameter 8 below)

P6 = added thickness.  Default for heavy bars = 4.
       Ordinary thin bars and dashed bars may be thickened with p6.
       (For hard copy ALL thin bars and dashes become double thickness.)

P7 --  This may be used for the horizontal displacement of a bar.  Its
       usual use is to position a brace (curved) to the left of a bracket
       in an orchestral score.  When p7 is used, the various justifying and
       spacing routines will not change the brace's relative position.

*

P8 -- Partial heavy brackets (p5 = 9) may be made by using p8.
      P8 = 0 = end units of bracket appear at both top and bottom.
         = 1 = end unit appears only at top.
         = 2 =  "   "      "     "   "  bottom.
         = 3 = vertical part of bracket only. (No top or bottom units.)
   Use these (in conjunction with p10, p11) when preparing large orchestra
   scores, where several separate files may be needed for a single complete
   system of staves.


P10 = sets origin of barline (bottom).  (= 0 = default = 3, bottom line)
P11 = sets destination of barline (top).  (= 0 = default = 11, top line)

         The values are in scale steps.  If p10 is negative, the bar will
         begin below the staff.  If p10 = 11, it will begin at the top
         line of the originating staff.  P11 = 7 will cause the bar to end
         at middle line of destination staff, etc.
