Thank you, I've fixed that up:
"The arena is composed of a 2-dimensional array with dimensions arena[
metrics[WIDTH] ][ metrics[HEIGHT] ].
A unit at the cartesian coordinate {5,7} can be found at arena[5][7]."

Uh, not really... 
I understand what you're getting at though, and I think the best thing
would be to have a persistant state variable, and a big if statement
first thing in the get_orders() routine to decide what to do. The
performance hit is negligible, as the get_orders() routine is only
called once per turn, not per unit.

You are allowed to declare things at top-level like persistent data
structures, state variables, etc... you just have to initialise them
within the startup routine. This is because sometimes the program will
be executed without ever calling user code. (Look in the .ew file - if
it's called with 'about' as an argument, it'll send the name and
description to the GUI, then quit)
