Well, there are a few highlevel petri-net-tools, e.g.: pace, which allow
there tokens more to carry than colors but tupels of data which also can
mean (arg). The transitions are fully programmable, in pace
smalltalk is used, not my favorite, to manipulate the token-data. In my
opinion it is very boring and slow to program with the mouse. But at a
first look very impressiv and good for repeated demonstrations or to
people who have no programming skills.
