Description: uses a loop to plot 4 right angled triangles at different positions on the screen which, when completed, make up the star pattern.  The loop builds a string of star characters increasing from 1 to 13 which are plotted on screen in positions calculated as an X & Y offset from the current value of the loop.  In BBC BASIC, it is not necessary to declare a variable before assigning a different value to it, so vital bytes are saved by only adding to the star string during the loop without having declared it outside the loop.
