"The Classroom" by Michael Callaghan

Include Fixed Point Maths by Michael Callaghan.

The classroom is a room. A chalk board is in the classroom. Understand "chalkboard" as the chalk board.

Instead of examining the chalk board:

say "Someone has drawn a curve like a sine wave turned through 90 degrees.";

repeat with angle running from 0 to 360:

let val be the sine of angle;

let val be 40 real times val;

let plot be val as an integer;

let plot be 40 plus plot;

repeat with X running from 1 to plot:

say " [run paragraph on]";

let angle be angle plus 10;

say "*[line break]".

Test me with "x chalk board".
