Hi,

With context 2024.08.16 the following gives an error:

\starttext
$A \ldot B$
\stoptext

tex error       > tex error on line 2 in file ./test.tex: Control sequence expected instead of undefined

<line 3.2>
    $A \ldot
     B$

Same error with `\ldotp`. 

However

\starttext
\show\ldot
\show\ldotp
\stoptext

gives

> \ldot=permanent \Umathchar"02"00"00002E
> \ldotp=permanent \Umathchar"06"00"00002E

which appears correct. 

So, not sure what is going on. Any ideas?

Thanks,
Aditya

I have no idea what's the cause for the error but I can narrow it down.

When you replace \ldot with it's mathchar version you can reproduce the 
error when there is *no* space at the end, \ldots on the other hand has 
no problem without the space.

\starttext

No space at the end of \tex{Umathchar}:
$\Umathchar"19"00"002026\Umathchar"19"00"002026 $ % \ldots

Space at the end of \tex{Umathchar}:
$\Umathchar"19"00"002026 \Umathchar"19"00"002026 $ % \ldots

No space at the end of \tex{Umathchar}:
% $\Umathchar"02"00"00002E\Umathchar"02"00"00002E $ % \ldot

Space at the end of \tex{Umathchar}:
$\Umathchar"02"00"00002E \Umathchar"02"00"00002E $ % \ldot

\stoptext

good analysis ... quick hack to get Aditya going ...

\appendtoks
\amcode\commaasciicode    \zerocount
\amcode\periodasciicode   \zerocount
\amcode\semicolonasciicode\zerocount
\to \everymathematics

i need to ponder this (too late now)

Hans

Thank you Wolfgang and Hans. My old documents compile now, so I can wait for a proper fix.
