depending on the calc.... (a recently discussed issue on this list is inlcuding the calc you are talking about) for 82 and 83, the send command sends a variable to a CBL device or an external experiment. The Get command on the 82 gets a variable from a CBL device as well as on the 83 but on the 83 GetCalc gets a variable from another calculator. Eric "Dont ask why?; ask why not?"
