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.”
when you add stuff to the page it happens globally till (normally) tex
splits off the content that fits to the pagegoal (which is taken from
vsize) .. in principle we could leave hsize untouched but for
consistency and predictability we use textwidth etc .. this has always
been the case
