You're right. Thanks.

I feel honored to have my submission reviewed so thoroughly.

The one change I fail to see the motive for is the decision not to initialize @prev_cells when it is declared, but instead to test for its existence on every pass through the loop.

Mostly 'cause I didn't notice you initialized @prev_cells until after I already had the `if` in place. :) I have no problem with how you did that. (Mind you, $SPACE works just as well as the empty string.)	[reply] [d/l]
