it's there for a reason. If you execute the loop only one set of ... time.
Although this is somewhat interesting, it isn't what I intended. The FOR loop causes "persistence" sets of points to be generated without any being erased (note that only Gen(p) is called, with color equal to one). So when the WHILE loop below this is reached, the call to Gen(e) will erase points that were plotted "persistence" interactions earlier.The values of p will always be"persistence" interactions ahead of e. Thus, you'll always have at most "persistence" sets of points on the screen at any given time.

Those of you who have an Action! cartridge should try this program. It's very small and easy to enter. The first thing you'll notice is that it doesn't run especially fast, This is mainly due to the fact that it is using the Atari operating system's PLOT subroutine. In Part II of this series, I' ll discuss some things you can do to speed it up. You may also wish ~[....] the best looking patterns.
