11 <= |n| <= 99 means fill with dot pattern.
A dot pattern is of the form: uv, where the digit u is the increment
number of dots to light up horizontally, 1 <= u <= 9, and the digit
v is the increment number of dots to light up vertically, 1 <= v <= 9.
For example, a dot pattern of 34 means to light up every third dot
horizontally and every fourth dot vertically.
1 <= |n| <= 10 means fill with hatch pattern. When <Bn:m> is entered,
the two hatch patterns |n| and |m| are used to fill the characters.
A hatch pattern is composed of an angle and one to ten spacings.
These spacings are simply cycled through as each character is being
filled, that is, a line is drawn inside the character at the
specified angle, then a parallel line is drawn at the first spacing,
then another parallel line is drawn at the second spacing, and so on
for the number of spacings in that pattern. This process is repeated
until the character is filled. There are ten hatch patterns
available, which can be re-defined with the SET HATCH command.
