Bob, Thanks for your comments. Good catch about adding the [Converter Parameters] to the table and keyword tree. Regarding your questions on the parameters, here are my quick reactions. We can have more discussion on it as necessary. The Booleans might be needed for *-AMS models which can have such parameter types, so I would think that we should support them too. Starting each parameter assignment on a new line is fine with me, I just thought that we could make things a little more efficient this way, but I am fine with new lines too. Regarding default, you are correct that the called IBIS-ISS or *-AMS files might have their own defaults, but this is not guaranteed. But I think you are incorrect about saying that "all of the tree definitions have default values". The Default in the tree definitions are really a default for the selection from a multi valued parameter (list, range, etc...) so that there will be a value even if the user doesn't make a selection. But this mechanism doesn't guarantee that the IBIS-ISS parameter will always have a value, even if the parameter or tree from which the value supposed to come from is not found. I don't mind leaving out the default value from this parameter assignment syntax, but I want to make sure we all know what this would have done for us, and what we will be missing if we don't have it...
