note Jasper I should probably also note here that my original 'equation' used <code>$_ || $"</code> in the final print. So that first formula x and y are the actual coordinates of the clock indicies. <br><br> Later, when I moved to <code>print "@$_"</code>, I had to fiddle the numbers a bit to generate the numbers above, because there is slightly different spacing caused by the undefs (one extra space, if I'm thinking correctly on this very hung over afternoon). These aren't then the x and y coordinates, but the print sorts all that out. <br><br> Anyway, just an explanation in case any eagle-eyed readers wondered what was going on there... 811919 811926
