Description:
<The box is broken in 3 parts
1) the knot
2) a line
3) a half box
The knot is set using the TAB from the ROM and then displaying the knot
A line is a first character then 2x (8 characters and a first).
The box is the same as a line, 1 top line and 2x halfbox.
Each half of the box is drawn recursively which saves 2 bytes for a JR NZ-test.
