    /* Coding tip: 

       NEVER EVER use a format like "%6d%6d%6d". This will nicely
       format your three numbers in 18 spaces just like " %5d %5d %5d"
       and save you three bytes of static string space. However, when
       the numbers suddenly become a bit larger than you expected
       you'll end up with unexpected results: just one huge number
       instead of three separate numbers. This especially matters if
       the reader of the info is a program and not human.  */
