Re: Some symbols of mathematical calculus missing?

Thanks for nabla.
I can handle the commands for multiple integrals by myself in the way I sketched before. 

Contour integral \oint is working but not correctly in my case. This code:

\starttext
\startformula
\oint\limits_{\partial S} \vec{F}\cdot{\rm d}\vec{l}=\mathop{\int\!\!\!\int}\limits_{\bs S\phantom{M}} \vec{\nabla} \times \vec{F}\cdot{\rm d}\vec{S}
\stopformula
\stoptext

gives the result in the attachment (I know I can typeset it by a combination of \circle and \int or something similar, my point is just to show the problem with \oint).

Thanks for help,
Best regards,
Tomas
