are you sure that plain eqalignno produces a number?

$$\equalignno{...\cr...}$$

does not give me a number in plain

anyhow, you can get numbers with by adding

   \formulanumber

to the lines you want them

this is already repaired in the latest version, now there is also

\definemathcommand [integers]       {\blackboard{Z}}
\definemathcommand [reals]          {\blackboard{R}}
\definemathcommand [rationals]      {\blackboard{Q}}
\definemathcommand [naturalnumbers] {\blackboard{N}}
\definemathcommand [complexes]      {\blackboard{C}}
\definemathcommand [primes]         {\blackboard{P}}

this is also supposed to work with the palatino and cmr/ams math [from now 
on, ams is preloaded as fall back]
