Thanks. This works indeed. But what to do in the following
case? It's hard to find a proper wording for this problem which
makes searching on the net or in the documentation difficult.

\starttext

\def\cmd
  {\newdimen\mydimen
   \mydimen=50pt}

\startluacode
  context.cmd()
  if tex.dimen.mydimen < tex.dimen.textwidth then
    context("is smaller")
  else
    context("is not smaller")
  end
\stopluacode

\stoptext
