Hi,
When I run Example 1 given there, I get three bullet symbols, but no "column N ..." text.
Note that the \starttext is *after* the \startitemize ... \stopitemize
Q1: Is my ConTeXt installation broken, or is the wiki page showing output that does not correspond to the input?
Q2: If the wiki page is inconsistent, is there an easy fix?
Q3: If my installation is correct, why do I get bullet symbols *before* \starttext ?
Thanks.
Jim

The wiki adds \starttext at the start and \stoptext at the end of each example and the \starttext/\stoptext pair which is part is just ignored.
When you try to run the example as is there is no text before \starttext because no font has been loaded yet (you can add \setupbodyfont[modern] before \startitemize to make the text visible).

Hi Wolfgang,
Thanks for the (prompt!) answer.
I did not realize the wiki software did that. On reflection I suppose that is useful in many (most?) cases. But I'd argue that it is not always a good thing, such as in this case. (If nothing else, it might mislead a n00b into thinking that you should get output for text preceding \starttext.)
If you (or some other knowledgeable person reading this) don't (doesn't) mind another question,... Is the bullet symbol not from some font? If so, why is that font loaded in time to see the bullet?
And finally, might it make sense for the wiki software to do something like this: if grep '\starttext' <the-wiki-example-to-be-compiled> >/dev/null 2>&1 then process the example from the wiki else augment the wiki example with \starttext and \stoptext process the augmented wiki example fi
Cheers. Jim

The reason why you get no text isn't that you wrote it before \starttext but that no font was loaded yet. By default ConTeXt postpones the loading of the default fonts until \starttext because when you use a different font on your document this is normally before \starttext and with the postponing there is no need to load a unused font.
At the point where you load a font with \setupbodyfont text even if it appears before \starttext is shown as expected but this isn't recommended.

When no font has been loaded yet with \setupbodyfont ConTeXt prints text which is put in a \hbox in a monospaced font as shown in the example below.
%%%% begin example This is before \tex{starttext}.
\hbox{This is also before \tex{starttext}}
\starttext This is after \tex{starttext}. \stoptext %%%% end example

Hi Taco,
thanks very much for the link. But, ummm, what it says there seems to contradict what Wolfgang told me in the other response to my message.
[[ I see Wolfgang edited the \blank wiki page to move the text in question to after \starttext, but I'm sure if you don't believe what I say in the next paragraph, you can grab the previous version. ]]
Specifically, the example in the (previous) \blank wiki page does, indeed, have a \starttext and \stoptext. So, according to the page you mention above, another \starttext and \stoptext should *not* be added. And yet the (previous) \blank page example does print the text (as well as the bullets) before the \starttext. Is there a discrepancy between what .../Help:Context says and what actually happens?
Thanks. Jim

When you take a look at the settings which are applied here you can see \setupbodyfont[8pt] which is the reason why the text appears, compare
%%%% begin example Before \tex{starttext}
\starttext After \tex{starttext}. \stoptext %%%% end example
with
%%%% begin example \setupbodyfont[12pt]
Before \tex{starttext}
\starttext After \tex{starttext}. \stoptext %%%% end example
The second example loads a font before the text appear in the document which is the reason why you can see it.

Thanks Wolfgang,
all is now becoming clear. :-)

P.S. Well, "all" about this, I still have lots of questions about other things.

Thanks again. Without looking at the code, I (boldly) conclude that the bullet is in an \hbox.
While I'm curious about why text in an \hbox is printed, I'm thinking that I may not have need to know. ;-)
