One more thanx Hans for interesting and useful information

BTW: I did not get an answer to my last mail see Re: [NTG-context] CSV
scanners built in ConTeXt - feature or bug?
I wrote that now is splitter works properly. I would like to ask if
you're planning to fix file util-prs.lua in a future release of
standalone ConTeXt?
As for me, I'd rather vote for as the default option other option, ie
which does not stop on a blank line ie. not how it's setup now (ie
personally I'd rather vote strict=true would mean process all lines of
CSV file and strict=false mean stop processing on blank line), but I
will take into account whatever alternative and consequently I would
take into account this options for my own library.
Alan writes about this behavior as like metapost feature. Personally, I
think that the CSV file is basically a plain text file and a blank line
in it has its place. The end of the text file is usually marked by <eof>
character, so I guess there's no reason to terminate processing before
the file really ends.

Hello ConTeXist.
Petr Olsak (maintainer of Czech/Slovak support for TeX) helped me with
simple typing of sign charts. He made a PlainTeX macro who is working
too in ConTeXt (see
http://tex.stackexchange.com/questions/230273/typing-of-math-sign-charts).
Petr Olsak (not ConTeXt even LaTeX user) was modified PlainTeX
macro to
work in ConTeXt and asked the question:
"Does anybody know why ConTeXt sets catcode of & to 12? This means
that
it is incompatible with plain TeX".
Which is imo no big deal.
I did not write that he would give redoing some work, after discovering
that catcode & is different than in plainTEX.
May I therefore ask , what is the reason that has character & catcode
other than in Knuth PlainTeX?
There are catcodes of other characters incompatible?
Because the context table mechanisms don't use & (and never used it)
so ther ei sno reason to make & special. The _ and ^ are also normal
characters. For now we keep the $ for math (and in math mode the & ^ _
work as expected).
Although we're to some extend plain compatible it's not our aim, just
like we're not amstex, latex, lamstex or anytex compatible.
Ok. Thanks for the explanation. I wrote to Peter that developer context
to have a reason, and certainly it would from an ordinary whim not done.
Even so, I am very satisfied with the degree of compatibility.
Practically all of my old PlainTeX macros in ConTeXt work fine.
\pushcatcodetable
\catcodetable\texcatcodes
your plain code
\popcatcodetable
but it doesn't help when sources are passed as arguments of macros
under the normal regime
Thanx
