Hi friends,
In David's mail I found one of the problem I had been thinking of too, and I tried his code. Unfortionately, it does not work.

I don't need it for math, but for case descriptions.

A case consists of the following elements:

Case 1    Eating fruit is healthy
Text text text - case description --

1. abcd
2. efgh

1. aaa bb
2. dderere

Case 2   Everything about vitamins

The elements themselves I can put in blocks in order to be able to separate the q's and a's.

What I am wondering about is how to include the title in the macro.
It does not seem very difficult, but I can't figure out how.

The theorem environment seemed promising, but David's suggestion does not process. Has anyone an idea?

Kind regards,

In the meantime, I solved the second part, i.e., adding the additional

% MathParagraph is the enumeration (it ensures references and numbering,

\def\dostartLemma[#1]#2 {%

So I can use
\startLemma[reference]{Algorithm xyz terminates}

I came to the idea to misuse command= to typeset the header and write to
the list, it is given an argument containing the number of the enumeration.
Anyway, it is not easy to feed it into \expanded{\writetolist...} as the
argument is something with \edef and a pile of pretty ugly macros :-), so I
still use \precedingsectionnumber\numberMathParagraph :-(

To sum up, a good way to obtain current enumeration number (in a form that
goes into lists, etc.)  would be completely enough, provided that one
writes hacks to solve the rest (and does end up finding the real macro
names with \tracingmacros=1 :-)). Creating something like
enumerateddescription (a description with names and possibility to write
lists) would be much nicer, of course :-))

Thank you very much,

P.S.: Hans said once that a Dutch mathematical journal is typeset with
ConTeXt. Do you have an idea how they typeset theorems?
