\setupblock[NLblok][before=3D{\mainlanguage[nl]},after=3D]

\setupblock[ENblok][before=3D{\mainlanguage[en]},after=3D]

Then, determine = which blocks you want to use in your file:

\hideblocks[NLblok]

%\hideblocks[ENblok]

For the titles I use another = method:

%\def\NL#1{#1}

\def\NL#1{{}}

%\def\EN#1{}

\def\EN#1{#1}

You have to = comment and uncomment, depending on the language, but I think you can = put them in the NLblok or ENbloks instead.

\definecomplexenumeration[Casus]

=E2= =80=A6 definition

\def\refno#1{{\em{(no. \small #1})}}

My files look like this:

\starttext

\startCasus[casus-349][\NL{Een moeilijke zaak}\EN{A = complicated case}] \refno{casus-349}\crlf

The casus-349 element is used as a = label. After the text I have a list of questions for this case in a = separate block for questions, introduced by \in[casus-349]).

You can probably also = use something like

\section[\NL{Een moeilijke = zaak}\EN{A complicated case}]{xxxx}

\begin[NLblok]

\startlinenumbering

text ...

\stoplinenumbering

\end[NLblok]

\begin[Enblok]

\startlinenumbering

text...

\stoplinenumbering

\end[Enblok]

\stoptext

I hope this helps finding a solution.

Dear list members,

I write training = manuals and use the Modes mechanism a lot to create documents at various = competency levels using a single set of source files. So far the manuals = have been written in English but now a separate Dutch translation has to = be created.

It is important that = the two manuals are setup similarly so the section/subsection numbers = and question numbers are the same in the English manual and the Dutch = manual. Note: I do not intend to create a manual that has the English = and Dutch text at opposite sides (as can be done using streams)

I=E2=80=99m keen to continue using a single set of source = files and thought it would be best to simply type the translated = sections and subsections just below the original English sections and = subsections using modeset. This gives me the option of creating an = English case and a Dutch case. Within this two cases I would still apply = all sorts of other modes using \startmode and = \doifmode.

I have done = that with LaTeX and IMHO that way lies madness. It may work for shorter = text but for text(s) of any length it gets messy. You lose the = "flow" in both texts, and it shows when you read the typeset text, = and the source becomes hard to navigate. You are probably better off = using an editor which allows you to have the two versions open side by = side in their own viewports (I use what Vim calls "windows"). If = each section heading is on its own line you might try something like a = Perl script to loop over the lines in the English version and print only = the section headings to a new file, where you translate them and build = up the Dutch version around them. It's even better if the editor has the = capacity to show an outline pane for each version =E2=80=94 if there is = an outline mode which understands ConTeXt.

I'm sorry = to discourage you but chances are that you end up with an intractable = mess which you will have to spend much time disentangling = later.
