try it again
assign counter = 0
flow
assign counter = counter +1
assign counter = counter +1
If atomic means infinitesimal, then I would interpret it to mean the two
activities cannot happen concurrently (logically speaking), and the
result is counter = 2.
If atomic means indivisible, then I would interpret it to mean that the
two activities cannot be interspersed, but could occur concurrently, and
the result could be counter = 1.
