Hallo Holger, hi all

I use
\eqalignno{
  left & right & \formulanumber \cr
  left & right & \formulanumber \cr
}

or

\eqalignno{
  left & right & \formulanumber{a}    \cr
  left & right & \subformulanumber{b} \cr
}

If I have a longer formula which should only get one number, I use

\eqalignno{
  left & right1 &                  \cr
       & right2 & \formulanumber{} \cr
}


With warm regards also from Berlin,

Tobias
