All: I support working with the current BIRD text. I also appreciate the amount of work and experience that it represents and thank the authors for bringing it to IBIS. With respect to Format, here is a simple solution to to take the Version issue off the table and address all concerns: A simple statement (exact wording and details to be worked on later): "The syntax 'XXX' and 'Format XXX' are equivalent representations of the same keyword that formerly required Format." Format never has to be mentioned again, and the existing BIRD can remove all other references to Format. No examples will use Format. This dual representation of a keyword provides trivial overhead for all EDA vendors and model suppliers that support IBIS-AMI now and for those in the future. It also supports clean documentation and certainly favors migrating to the cleaner syntax when it becomes official in Version 5.1.
