%%%% begin example
\newwrite\testwrite

\immediate\openout\testwrite=\jobname-testwrite.tmp

\parindent=1cm

\starttext

  \indent\pdfsavepos\write\testwrite{1:\number\pdflastxpos:\number\pdflastypos}

\noindent\pdfsavepos\write\testwrite{2:\number\pdflastxpos:\number\pdflastypos}

\page

  \indent\pdfsavepos\write\testwrite{3:\number\pdflastxpos:\number\pdflastypos}

\noindent\pdfsavepos\write\testwrite{4:\number\pdflastxpos:\number\pdflastypos}

\page

  \indent\pdfsavepos\write\testwrite{5:\number\pdflastxpos:\number\pdflastypos}

\noindent\pdfsavepos\write\testwrite{6:\number\pdflastxpos:\number\pdflastypos}
