There's nothing wrong with a structured jump without a label.

btw, next is listed in the manual along with break, redo, and retry.

Well, it's a little on the clunky side, but it works.

def doRows (grid,char)
   (0...3).each do |row|
     callcc do |nextRow|
       (0...3).each do |col|
	nextRow.call() if grid[row][col] != char
       end
       return true
     end
   end
   return false
end

Thanks for the help, I would have had a hard time finding that
on my own.
