It's probably a virus or virally related now that I look at the code for the simple reason that the repeated elements seem to form a gene.
start
angle rnd and
pyth inc
mod stop
This gene also seems to me (through the rnd operator) to randomly increment different memory locations, one of which could be the sysvars to make and fire viruses.
Note that it's the first gene at the start of the genome, so inc will manage to place it in a virus.
The more I look at it, the more I think you have something genuinely interesting going on, something unrelated to the program itself. Although it might soon become problematic as the DNA grows larger than your available RAM
This seems to me to be a runaway virus endlessly replicating itself and also being (somewhat) benefitial to the idiot bots it's infecting. At least benefitial enough that it doesn't kill the bot.
A true example of the "selfish gene" at work.
It is, however, alarming that the DNA deparser couldn't seem to break the code into genes properly for display ("''''''''''''''''''''''''Gene 0: Last 'stop' at position..., Gene 0? And not all stops are given gene counts)
