Structured cycle – one entry and one exit (while loop)
“Consider three activities named A, B, and C. Activity A is only enabled if activity B has been executed and C has not been executed yet, i.e. A is not enabled before the execution of B and A is not enabled after the execution of C. The state in between B and C is modeled by place m. This place is a milestone for A. Note that A does not remove the token from M: It only tests the presence of a token.”
