Good evening all,

the following example demonstrates my problem:

··8<·····························································

\showframe

\newdimen\tabcolsize
\tabcolsize=.25\vsize
\def\knuth{\input knuth\relax}

\startbuffer[sometable]
  \starttabulate[|p(\tabcolsize)|p(\tabcolsize)|p(\tabcolsize)|p(\tabcolsize)|]
    \dorecurse{5}{\dorecurse{4}{\NC\knuth}\NC\NR}
  \stoptabulate
\stopbuffer

\starttext

\placetable[here,split,90]{none}{\getbuffer[sometable]}

\stoptext

··8<·····························································

As you can see, I need some advice on how to restrain the
tabulate float from flowing over into the right margin. What
dimension do I need to set and to what value?

Thanks for your time
Philipp
