How much difference is in cisco command line and hp switches

How much difference is in cisco command line and hp switches command line

where can i find simulators for hp switches like cisco has packet tracer or boson

Just looking at this HP procurve config I can tell there isn't much difference save for a few commands, one thing HP does to make the crossover is use ! for comments:

As far as HP simulators go I don't think there are any that really exist because people build their sims for Cisco. If you find one feel free to post it here. There may be a way to make Dynamips do what you need but honestly I just don't know.
