and m must be 1.
The value of dl determines the location of the score:
1 = underline, 2 = strike-through, and 3 = overscore.
The value of d2 determines the line style:
1 = single continuous,
2 = double continuous,
5 = single broken, and
6 = double broken.
d2 = 0 cancels the score line selected by dl .
