The point of my question was: can I feed the content of tex.dimen["textwidth"] directly back to TeX, and the answer to this appears to be "no"; you need to add some unit to it (otherwise, you get an error message). Which was a bit confusing to me at first, because the name tex.dimen implies that it holds a "real" dimension, like \newdim does. > > > You can get the same value in TeX when you print the value of a dimension with \number: > > \starttext > > \scratchdimen=3pt > > \number\scratchdimen > > \ctxlua{context(tex.dimen["scratchdimen"])} > > \stoptext which also means that you can say \scratchcounter=\scratchdimen and test dimens as if they are numbers ... this is why we can have \let\ifzeropt\ifcase which probably no one ever noticed in the source.
