Onderstaand mailtje had ik via de NTG- Context lijst verstuurd maar is kennelijk gesneuveld in de gehackte server (zoals ik net via de email 'hoorde'). Daarom hier nogmaals

Equation numbers are produced by
\placeformula\startformula ... \stopformula
Not by
\placeformula\startformula\displaylines{ ... }\stopformula
as is according to plain TeX.
But also no equationnumber appeared with
\placeformula\startformula\eqalignno{ ... }\stopformula
where one should expect to see one.
How can I get my multiline displays numbered?
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

Een tweede puntje. Ik kreeg in lucida de blackboard letters (R, N, Z, etc. vooral voor math) niet.
Het mailtje naar de lijst (of het antwoord daarop) zal ook wel om dezelfde reden gesneuveld zijn.
Ik vond onlangs echter uit dat dit probleem kan worden opgelost door aan het bestand math-lbr.tex een regel toe te voegen. Misschien iets voor de volgende beta.
% HvdM 2002-10-09: next call activates \Bbb#1 for blackboard letters
\definefamilysynonym [lbr] [blackboard] [ma]
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]
