How could this be ? You say "each character has been
converted to one of 52 two-digit numbers (so, 01 through
52)" but [a-zA-Z] of itself will require 52 such numbers,
so what numbers are assigned to [0-9 . , ; : ! ?
\textemdash ...] ?<br>

<div>Well, for one, I'm ignoring capitalization. But again,
that part of the conversion has already been done, and
requires no further work. All I need is to convert the
resulting two-digit numbers into *other* two-digit numbers,
using the keytext.</div>

I will try once more, Andrew, but to be honest I am rapidly losing
interest, as trying to get <i>accurate </i>information from you
regarding the earlier stages of your processing is proving
extraordinarily difficult. <br>
<br>
So let me ask one simple question — if there were a processing
engine E that took as input your ciphertext.tex and keytext.tex
files and sought to produce your codetext.tex file, would that
engine E need <i>any knowledge at all</i> as to which fragments of
ciphertext.tex represent TeX-specific constructs such as \footnote
? If so, why ? Why can it not operate on ciphertext.txt with no
prior knowledge at all as to what its contents might represent ?<br>
