Okay.

What is the scope of local use?
It’s used to change the width of a \vbox.

\starttext

\ruledvbox\bgroup
    \input ward
\egroup

\ruledvbox\bgroup
    \hsize.5\textwidth
    \input ward
\egroup

\stoptext

It is different from grouping (as demonstrated by placing the middle two lines above in braces).
Which example?

Wolfgang

Sorry, the example at the head of the thread. Originally:
\starttext
   \hsize200pt
   \dorecurse{60}{\recurselevel: \the\hsize\ \the\textwidth\par}
 \stoptext

And with the \hsize in a group :
\starttext
   {\hsize200pt
   \dorecurse{60}{\recurselevel: \the\hsize\ \the\textwidth\par}}
 \stoptext

I did not expect it to change the result, and it does not. So I was asking just what Hans meant by “local use.”
