Draws Totoloto-like sequences to assess random assignment criteria. (The "luck" numbers are 1–13.)

Draws the probabilities.

Computation structure — A PHP file (this page: 'Fx-totoloto.php') calls (via 'action=') an intermediate PHP file ('TotoLoto.php'), which (through $_POST) sends the problem data as command line arguments to a Fortran 90 executable. This last does the computing, and makes 'system' call(s) to 'gnuplot', for the final (temporary) webpage. Keywords: PHP, command line arguments, Fortran executable, gnuplot.
