Launching One Pro-SiMPLE
Program From Another

By using the system task, it is possible to write a Pro-SiMPLE program that passes execution over to a second program.

To illustrate the technique, the following program: 

      Do
         line color (random (16))
         solid color (random (16))
         filled circle (random (640), random (480), 25)
         If read key ( ) Break
      Loop
      system ("DAZZLER")
      quit
will continue drawing randomly colored circles until any key is pressed. At that point, it will invoke the DAZZLER program which was presented in the Micro-SiMPLE tutorial. (For your convenience, the source listing for the DAZZLER program is replicated here.): 
       outer loop: Set x = 0
                   Set y = 0
       inner loop: Call solid color (random (16))
                   Call solid rectangle (x, 0, x + 15, 479)
                   Call solid rectangle (0, y, 639, y + 11)
                   Call solid rectangle (639 - x, 0, 624 - x, 479)
                   Call solid rectangle (0, 479 - y, 639, 468 - y)
                   Call delay (25)
                   Call read quit key
                   Set x = x + 16
                   Set y = y + 12
                   If x < 640 Go to inner loop
                   Go to outer loop


[NOTE: The technique, as presented here, assumes that the two programs are both
in the same project, and that the DAZZLER program has been previously compiled.]
