hsize changes unexpectedly
Why does \hsize revert to \textwidth after a page and a paragraph? \starttext \hsize200pt \dorecurse{60}{\recurselevel: \the\hsize\ \the\textwidth\par} \stoptext -- Rik

because the main text flow width and height settings are synchronized ... \hsize and \vsize are for local use ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

What is the scope of local use? It is different from grouping (as demonstrated by placing the middle two lines above in braces). -- Rik

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?

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.” -- Rik

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 -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
