The data stream uses letters to identify dot counts.
CAPITAL letters represent black dots.
lowercase letters represent white dots.
Using the coding chart below, the data stream for row 1 would
be written as follows:
Dot count:
Row 1: 4 White, 8 Black, 19 White, 8 Black, 4 White
Data Stream:
dHsHd
(4 white = d, 8 black = H, 19 white = s)
You can use multiple letter codes to indicate strings of
same-color dots. For example:
30 black dots = ZD
9 white dots = ccc
