[erlang-questions] Cannot get the hang of single assignment

[Tom Ayerst]

Hi,

I think I am missing something obvious here.  I was reading Jim Menard's 
account of writing a boids flocking simulator and wanted to have a go.  
Giving each Boid its own process was obvious but, I am very new to 
erlang and was then stumped. 

How should I track the state (position and vector) of each Boid?

All help appreciated.

Tom
