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
