Tobias,

Here is a final version. TeX's \halign is an unusually flexible construct,
but it's tough to become proficient in its use (I'm not. I much prefer the
macros provided by AMSTeX). Before you start thinking I am a TeX guru (I'm
not), I need to say that I stole the following idea from Donald Knuth's
"The TeXbook", page 334, example 22.9. The TeXbook ranks as one of the best
books that I own.

$$
\openup1\jot \tabskip=0pt plus1fil
\halign to\displaywidth{\tabskip=0pt
 $\hfil#$&${}#\hfil$\tabskip=0pt plus1fil
 & \tabskip=0pt$\hfil#$ & ${}#\hfil$
 \tabskip=0pt plus1fil &\llap{#}\tabskip=0pt\cr
\omega_1 & =\omega_0=\omega_{\rm s}
 &   Z_1&=\pmatrix{1\cr1\cr}={\bf Z}_{\rm s}
 & (a) \cr
\omega_2 & =-\omega_0=-\omega_{\rm s}
 &   Z_1&=\pmatrix{1\cr1\cr}={\bf Z}_{\rm s}
 & (b) \cr
\omega_3 & =\omega_0\sqrt{1+2f}=\omega_{\rm a}
 &   Z_1&=\pmatrix{1\cr-1\cr}={\bf Z}_{\rm a}
 & (c) \cr
\omega_4 & =-\omega_0\sqrt{1+2f}=-\omega_{\rm a}
 &   Z_1&=\pmatrix{1\cr-1\cr}={\bf Z}_{\rm a}
 & (d) \cr}

Well, you are a math guru, aren't you, so as soon as you enter mathmode
... 

Currently Taco is working on the context math module. Both the
bibliography and math module documentation will become avaible as an
up-to-date document (1999-005 and 1999-005). Now, how about an
additional up-to-date document with math examples, like the one we made
for chemistry? You already have a lot of examples, so providing a few
hundred examples should be possible. When you like the idea, we can make
you a guest editor of context up-to-date 1999-006. How about that?

Hi!

Speaking of which...
What exactly do we have to expect from the math-module?

Since the Ams stuff insists on printing "typeset by AmsTeX" in the
colofon of whatever you use it for, I don't want to use amstex.tex.
Instead, I'm using Michael Downes' breqn code. This has quite some
effects on the way you write these things (not so many environments,
but the ones that are there have options).

Hold on for a little longer, please. There'll be some stuff to test
later this week.

Since context is still essentially plain.tex, I'd say \halign

Currently working on the math stuff, but that will still be a few days
yet before there is anything usable.

[Tobias Burnus]

Hi,

since we have some TeX and math experts on the list, how can I best align this:

{\omega_1 =\omega_0=\omega_{\rm s}}               {Z_1=\pmatrix{1\cr1\cr}={\bi
Z}_{\rm s}} \formulenumber{a}
{\omega_2 =-\omega_0=-\omega_{\rm s}}             {Z_1=\pmatrix{1\cr1\cr}={\bi
Z}_{\rm s}} \subformulenumber{b}
{\omega_3 =\omega_0\sqrt{1+2f}=\omega_{\rm a}}    {Z_1=\pmatrix{1\cr-1\cr}={\bi
Z}_{\rm a}}\subformulenumber{c}
{\omega_4 =-\omega_0\sqrt{1+2f}=-\omega_{\rm a}}  {Z_1=\pmatrix{1\cr-1\cr}={\bi
Z}_{\rm a}}\subformulenumber{d}
