Hi,
now I noticed that I can even use some non-existing alignment:
\setuppapersize[A5]
\setuplayout[location=middle,
header=0pt,
footer=0pt,
height=fit,
width=109mm
]
\setupindenting[next,\baselineskip]
\indenting[yes]
\setupalign[nonexisting]
\starttext
Today, automated typesetting is quite popular, which is partly due to the fact that
document coding standards have evolved, in particular XML. For instance, when you
navigate the internet, a typesetting engine is at work to render the pages. When you
ask for a print preview, you often get a different rendering. So, one document source
can result in different views.
The vehicle that we use for automated typesetting of books is called CONTEXT. This
system is based on the well known typesetting engine and language TEX and the
graphic programming environment METAPOST.
\stoptext
This example is processed without errors although there is no definition
of the alignment "nonexisting". Is it not strange?

When ConTeXt parses the \setupalign command it looks if the keyword is defined
and executes it but when the keyword isn’t defined its just ignored.

thank you for your explanation. So probably my definition of new
alignment "block" was not successful and when using \setupalign the
alignment with the keyword "block" is simply ignored.
Is there any possibility to find out if the new alignment was really
defined and exists?
\installalign
{block}
{\parfillskip=\hsize
\advance\parfillskip by -1.5\parindent
\advance\parfillskip by 0pt minus \parfillskip
\advance\parfillskip by 0pt minus -1em}
% Next command is probably ignored? Can I test if the alignment "block"
% really exists?
\setupalign[block]
Best regards
Pavel
