looks pretty low level to me -)

\startformula[for:a]
a formula
\stopformula

as we see in \in {formula} [for:a] ...

\placeformula

[Albrecht Kauffmann]

Hi all,

is there any documentation of the commands \placeformula,
\startformula, and so on?

With many thanks for any hint

you can find details in core-mat.tex

(reminds me to finish updating the main manual -)

also, if you don't tell the others, you may peek into

no problem, i'll upload a newer one later (more examples of the extended

i can probably build that into columnsets one day; on the other hand, 
columnsets provide you a means to position graphics directly

\definecolumnset[mine][n=3]
\setuppapersize[A3][A3]
\setuptolerance[verytolerant]
\setuplayout[backspace=1cm,topspace=1cm,width=middle,height=middle]
\setuplayout[grid=on] \showgrid \tracecolumnsettrue

\starttext

\startcolumnset[mine]

\placefigure[rltb]{}{}

\placefigure[fxtb:2*13]{}{}

\dorecurse{10}{\input tufte \par}

\stopcolumnset

\stoptext

this works ok with the beta i just uploaded

I tried and now it works.

By the way, I found the typo in type-buy.tex (I just reported) has been 
corrected also. thanks.

I am using  the following version:

reference problem

[Albrecht Kauffmann]

Hi all,

I have a problem with references to equationnumbers.

Let \the\equationnumber be 1. If I type

\reference[a]{(\the\equationnumber)}$$ (a formula) $$
\advance\equationnumber by 1
\reference[b]{(\the\equationnumber)}$$ (another formula) $$
... \in[a],\in[b] ...

I expect to get "... (1),(2) ...". With an older version of Context
(2000.12.14) this works fine. But with the new version (2002.10.23), I get
for both equation a and b the same number (namely the last, 2):
"... (2),(2) ...".

Is this a bug, or has somewhat changed?

With many thanks in advance
Albrecht
