Hi everyone,

I'm brand new to Processing.  I have a beginner's question.  I've just been reading through the book and working with the examples given there and trying out some things myself.   When I try to run some code that I wrote, the Sketch window does not appear.

What am I missing?

Here is the code:

for (int a = 10; a <= 100; a += 10) {
  for (int b = 10; b <= 100; b += 10) {
    for (int c = 50; c <= 500; c += 10) {
      for (int d = 70; d <= 700; d += 10) {
       for (int e = 90; e <= 900; e += 10) {
        for (int f = 80; f <= 800; f += 10) {
         triangle(a, b, c, d, e, f);
        }
       }
      }
    }
  }
}


thanks in advance,

Adam
