Those names are what we use in our programs to represent such or such enumerators *but* we also use these names for the to|from String operations used in the standard I/O operations (a literal RED of an enumeration COLORS would be output in the string "RED" and conversely a string "RED" read into a enumerator of COLOR would result in RED) ; therefore the external (string) representation of our enumerators obey to the rule which command the syntax of their names in the enumeration. This is probably what is frustrating Barry....</div><div><br></div><div>Michel</div><div><br></div><div><br></div><div>Now beside this, it's always possible to invent a mechanism different from the enumeration construct in order to represent a set of discrete values , but then </div><div>Le 18 févr. 2010 à 15:59, Francois Viallefond a écrit :<div><div><br class="Apple-interchange-newline"><blockquote type="cite"><div>On Wednesday 17 February 2010 21:51, Barry Clark wrote:<br><blockquote type="cite">I could be wrong but I think the OPT internally uses baseband names<br></blockquote><blockquote type="cite">A0/C0 (implying 8 bit), A1/C1, A2/C2.
