Hi,
I have something like this:
--------------------------------
\placeformula
$$
\eqalignno{
h\nu &=E=c\frac{h}{\lambda}&\formulenummer{a}\cr
\Rightarrow \lambda &= c\frac{h}{\Delta E} = (247\pm3)~{\rm nm}
&\subformulenummer{b}\cr
\Rightarrow \nu &= \frac{\Delta E}{h} =
(1{,}21\pm0{,}02)10^{15}~{\rm Hz}
&\subformulenummer{c}\cr}
$$
\bye
---------------------------------
it was definitly working, but now it causes error messages.
If I remove the \placeformula (and replace the \[sub]formulanumber by ""
(so a, b and c remain)) everything works as expected.
Please send me a bug fix soon.
Tobias
PS: The error message is:
