Your helpfulness is appreciated.  Unfortunately at age 68 my eyesight is not
what it used to be.  It works fine when I insert to missing comma.  Ah!
Programming is a young person's game.

anarray = [[1, 2, 3], [4, 5, 6], [7, 8, 0]]
puts anarray[1][1]
puts anarray[0]
puts anarray[2][0]

produces (SciTE)

>ruby test_2_dimensional_array.rb
5
1
2
3
7

I'm writing a move method for the 8-puzzle problem for my artificial
intelligence class and need a two dimensional way of representing the
positions of the tiles.

Again, thanks.
