would be one way to do what you want.
Yes, that's along the lines of what I was thinking — the 1..10 needs to be bound by itself to trigger the looping behavior, but didn't know how to then continue to generate (x,y,r). I thought the comma there was followed by a "guard", which constrains which values of i are taken or skipped. Ah, you have a <- there too. Hmm, but normally a second <- is another iteration that's done first/loops faster. So what's the syntax here? I must be getting things mixed up. —John
