I took the EBCDIC names from the current reference, and do indeed note the
fact that the names have changed over the years, and include a table of
original names for reference. Is there any sentiment in favor of actually
encoding the old names?

By the way, I also omitted the mnemonics of numerous special-purpose control
sets found in the ISO Register since, to my knowledge, no terminal ever
displays these mnemonics in "display controls" mode, nor does any kind of
protocol analyzer or data scope. I think people who look at "display
controls" screens will be satisfied with the proposed familiar set of
mnemonics. But I could be wrong.
