Seems to be a MATLAB-like programme. Useful for mathematical simulations. I don't see a hierarchical diagram editor anywhere, but I haven't looked to closely. Source available and free of change, but not free software. > flowdesignerhttp://ptolemy.eecs.berkeley.edu/ptolemyII/ptII5.0/ptII5.0.1/do >c/index.htm BSD licenced (but requires a Java runtime), claims to be similar to Simulink. It's not just a drawing programme; it's a simulator, and a rather complex one to my untrained eye. It does discrete events, continuous time (analog circuits), synchronous data flow, state machines, communicating sequential processes (Hoare), distributed discrete events, process networks, and a few others. Especially the process networks simulation seems interesting in this context. It simulates a network of processes that communicate via FIFOs. I'm not sure from the manual whether it does hierarchical systems though. I think this is the closest we've got so far, so if you have a bit of time Timothy, maybe you should check it out. Lourens
