First look into bytes encoding make no sense, need to look deeper into this.
After 40 years, I still discover things on the HP-41 ... or re-discover due to ageing

Hi Sylvain,
just found an introduction on how to calculate XROM-Numbers from the byte-table in Keith Jarret's book HP-41 Synthetic Programming made easy: p. 86 ff, Chapter 4C, Pseudo-XROM previews.
Greetings, Juergen
