User-defined Characters
Since NLQ characters can have up to 18 dots in a column, each
vertical column must be divided into three sections for data
number calculation.
The figure below shows a single column to make clear how the
data numbers are calculated. When designing NLQ characters, you
should use circles instead of dots to make it easier to see and count
overlapping dots.

To calculate the data numbers for this column, just add together
the values in each section of the column. If no dots are used in a
section, the data number is zero. You must use three numbers,
even zeros, for every column when writing the DATA statements
for a program.
