Hi,

In the first run I collect several ImageMagick commands in a common
batch file, which should be executed afterwards. A second run is also
needed to include the created graphics.

I tried

\appendtoks\mycommand\to\everygoodbye

but that does not work properly, if only one run is needed otherwise. So
I need to tell ConTeXt somehow, that an additional run is needed (adding
the number of runs to the command line is no option).

Currently I use

   if tex.modes["*first"] then ... end

to detect the first run. My first try was to add an 'else' condition to
call the batch file once, but sadly this is also not triggered in case
of a single run...

What is the official way (mkiv) to add a call at the end of the first
run (or the beginning of the second run)? And how can I ensure, that a
second run is forced?

Peter
