Hello,
one more problem - paper height still 297 mm?
----
\definepapersize[A4L][A4,landscape]
\showframe
\starttext
\setuppapersize[A4L]
A4L
\stoptext
----
(Ctx already patched by WS' solution.)
Best regards,
Lukas

%D Before you start wondering why some of the page related
%D modules skip upward or left in order to place elements, you
%D must realize that the reference point is the top left
%D corner of the main typesetting area. One reason for this
%D choice is that it suited some viewers that displayed page
%D areas. Another reason is that margins, edges and top and
%D bottom areas are kind of virtual, while the header, text
%D and footer areas normally determine the text flow.
\unprotect
%D The dimensions related to layout areas are represented by
%D real dimensions.
\newdimen\paperheight \paperheight = 297mm

%D The next series of dimensions are complemented by left

\newdimen\margindistance

%D Because a distance does not really makes sense when there
%D is no area, we use a zero distance in case there is no
%D area.
%D The horizontal distances are:
\newdimen\leftedgedistance
\newdimen\rightedgedistance
\newdimen\leftmargindistance
\newdimen\rightmargindistance
%D The vertical distances are:
\newdimen\topdistance
\newdimen\headerdistance
\newdimen\footerdistance
\newdimen\bottomdistance
%D We need to calculate the extra distances:
\newdimen\naturalmarginwidth
\newdimen\naturaledgewidth
\newdimen\naturalmargindistance
\newdimen\naturaledgedistance
\newdimen\naturalleftedgedistance
\newdimen\naturalrightedgedistance

%D The default dimensions are quite old and will not change.
%D The funny fractions were introduced when we went from fixed
%D dimensions to relative ones. Since \CONTEXT\ is a dutch
%D package, the dimensions are based on the metric system. The
%D asymmetrical layout is kind of handy for short
%D quick||and||dirty stapled documents.
%D
%D Although valid, it is not a real good idea to use
%D dimensions based on the \type {em} unit. First of all,
%D since there are no fonts loaded yet, this dimension makes
%D no sense, and second, you would loose track of values,
%D since they could change while going to a new page,
%D depending on the current font setting.

%D \CDROM\ covers, but it does not hurt to have the paper size
%D ready.
\definepapersize [CD] [\c!width=120mm,\c!height=120mm]
