Laurie, you are smart to have put a lot of thinking into this transcription before diving in and finding out later that much needs to be redone. Regarding our previous discussion about the IP addresses, subnet masks, and binary representations, I still support the use of Nemeth code for them within the narrative because they are also being used in math context with the equals sign.
I see that my reference to GTM 2.9 is misleading. Since Nemeth Code has clear rules regarding hexadecimal numbers (although it doesn't actually call them that), I would use Nemeth Code in this Nemeth/UEB transcription. Regarding Kyle's response to your table in the post entitled “Networking manual” in this forum, I agree with her suggestion that all three columns should be done in Nemeth Code.
