Thank you Walter for writing this proposal. I was hoping to address this topic one way or another, and your document is a good start in that direction. I will have to read it to see if it addresses the questions I had in my mind... Thanks, Arpad =============================================== From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Walter Katz Sent: Thursday, March 24, 2011 11:35 AM To: IBIS-ATM Subject: [ibis-macro] BIRD to clarify Usage Out and InOut parameters. All, There seems to be continued confusion on what the DLL is required to do for Out and InOut parameters, and what the simulator is required to do with the values of Out and InOut parameters returned from the DLL I am enclosing a BIRD that should clarify this. If we can agree on the content of this BIRD, then these rules can be incorporated in the numerous other BIRDs that are in process.
