The program below reads lines and creates an array of arrays (a
two-dimensional array), each inner cell contains a single character:

-------------------------------------
#!/usr/bin/ruby -w

data = "11XX22X1XX12X23\nXX12XX122X212X2\nXX2X11XX11XX111\n"

lines = []

data.each do |line|
   lines << line.split("")
end

p lines
-------------------------------------
