I'm pointing out the issues with the "subject" definition. Did you want me to quote the entire spec? > They're 2 different kinds of beast. If you eliminate or ignore the "Stored Message" definition from the spec, then it would be less contradictory. I also think the Stored Message definition doesn't really belong in the same spec as the packet definition. > And do you also know where the "71" comes from ? Well, I took 72 and subtracted 1 (for the required null byte). I assume the 72 came from 36 (the total length of the to and from fields) multiplied by 2. Is there some other significance of 71 that I'm not aware of? .
