Hi TeX-freaks,
We have an 8 bit emacs and we want to run TeX3.0 to use German specific
codes. I tried the following, but it don't runs. Can anybody help me?

It wont run. I tried it with the catcode block first, no success. I tried
to use the 'normal' letters of emacs8, no success. I get spaces instead
of the codes.

So you should give the constants in octal. 2) You need to tell that these constants should be interpreted as characters. Here is what I use to get various "accented" characters; the undersores (_) denote the actual 8-bit characters given as octal to the right: \catcode`\_=\active \def_{\`a} % \340 \catcode`\_=\active \def_{\c C} % \277 \catcode`\_=\active \def_{\c c} % \347 \catcode`\_=\active \def_{\'e} % \351 \catcode`\_=\active \def_{\"\i} % \357 Regards, Kristoffer H{\o}gsbro Holm <kris@diku.dk> Computer Science Dept.

Provided you run the web2c-version of TeX-3.0, the reason you can't
make it work is that US programmers simply don't understand the
concept of eight bit clean programs. (It's true, too many of them don't). The
following patch to tex-3.0/web2c/tex/extra.c will fix the problem.
*** O.extra.c Mon Sep 17 12:53:36 1990
--- extra.c Mon Sep 17 12:56:23 1990

*** 390,400 ****
if (f == stdin) clearerr(stdin);
#endif
while ( last < bufsize && ((i = getc(f)) != EOF) && i != '\n') {
! #ifdef NONASCII
! buffer[last++] = i;
! #else
! buffer[last++] = (i > 127 || i < 0)?' ':i;
! #endif
}
if (i == EOF && last == first)
return(false);
--- 390,396 ----
if (f == stdin) clearerr(stdin);
#endif
while ( last < bufsize && ((i = getc(f)) != EOF) && i != '\n') {
! buffer[last++] = i;
}
if (i == EOF && last == first)
return(false);
--------------------------------------------------------------------
It could of course be argued that a patch is not needed, there is an
#ifdef NONASCII, but in my opinion this is wrong, because NONASCII
refers to things like EBCDIC. The README file of the whole package
mentions 8-bit ASCII, which is a bit of a contradiction, but it
supports my view, so we'll let it pass :-)

> \def'228{\"a} \def requires a `command sequence' or an `active char' as first argument, otherwise ==> error "! Missing control sequence inserted." (Victor: It's not an octal number, it's a simple quote, then 3 digits, etc. and TeX doesn't expect a number after the \def token) Try something like this: \catcode228\active \def^^e4{\"a} % hex e4 = dez 228 The "^^e4" is read as one character, which is active at this place. > I tried to use the 'normal' letters of emacs8, no success.
