here are some hints: <ol> <li>You don't need to use characters, much less file i/o for this problem (unless you forgot to state that a file must be created).</li> <li>Therefore, use math to find your statistics. There are lots of <a href="http://en.wikipedia.org/wiki/Fibonacci_number" rel="nofollow noreferrer">resources on Fibonacci numbers</a> that might provide a simplifying insight or at least a way to independently spot check your answers. <ul> <li>Here is a complicated hint in non-Fortran lingo: <code>floor(10^(frac(log_10(7214989861293412))))</code> (Put this in <a href="http://www.wolframalpha.com/" rel="nofollow noreferrer">Wolfram Alpha</a> to see what it does.) </li> <li>A simpler hint (for a different approach) is that you can do very well in Fortran with simple arithmetic inside of looping constructs--at least for a first pass at the solution.</li> </ul></li> <li>Accumulate your statistics as you go. This advice would even apply to your character-driven approach. (This problem is ideally suited for coming up with a cute indexing scheme for your statistics, but some people hate cute schemes in programming. If you don't fear cuteness ... then you can have associative arrays in Fortran as long as your keys are integers ;-)</li> <li>The most important aspect of this problem is the data type you will use to calculate your answers. For example, <a href="http://www.wolframalpha.com/input/?i=calculate+the+1476+Fibonacci+number" rel="nofollow noreferrer">here's the last number you will have to print</a>.</li> </ol> Cheers, --Jared

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
