Wrong catcode?

Wrong catcode?

[Giuseppe Bilotta]

Hello, I'm using ConTeXt 2000.12.14

It looks like some <protection> leaked through some macros, since ? has
catcode 11 instead of 12. It's not my document's fault, since
\showthe\catcode`? gives 11 even at the very top of the file. This means
that things like \type{\dots?} cannot be used anymore (that's what happened
to me :->).

I believe this is a "recent" problem, since the previous format I was using
(2000.9.21) compiled the document flawlessly.

Ah, this is some optimization code that is etex specific and ends up in
normal tex mode. 

either comment 

  \readfile{font-exp.tex}{}{} % load local experiments

in font-ini.tex, or 

  delete font-exp.tex 

and in both cases regenerate the pdftex format, or even better: 

  USE PDFETEX ! 

but, i'll fix it anyway -)

Hm. Can you check cont-new.tex and cont-sys.tex for matching \protect ..
\unprotect? 

\starttext 

\def\test{test} \test? 

\stoptext 

should work. When reading module etc files, protection is handled, so maybe
some \unprotect lacks, When exactly does this happen?

cont-sys has an unmatched unprotect at the beginning (there is a \protect in
a commented block);
cont-new has 11 unprotect and 7 protects;

do these figures mean something to you?

In the document; something as easy as

\starttext
 Hello, World! This is \TeX!
\stoptext

shows the bug. Both ! and ? are of catcode letter rather than other.

Every \unprotect should be matched by a \protect, unless in a macro def, so
you can probably uncomment the \protect. 

If you give some 10 \protect's you get a warning -)

Adding a \protect at the beginning of my document solves the problem. So I
guess that the problem is the "naked" \unprotect in cont-sys.

I will change cont-sys and regenerate the formats, I will inform you of the
result as soon as I do it.

You shouldn't need to regenerate formats.  If you check a .log file
you will see that cont-sys is read each time context is run.  I have
already made the change on my system at work, and am about to do so
on my home system.

That's pretty good news, thanks :-)
