\newdimen checks for the existence of a control sequence
the point is that on minimals-beta there is an error, on minimals no , but xpdf says
Error: ExtGState 'Tr0' is unknown Error: ExtGState 'Tr0' is unknown Error: ExtGState 'Tr0' is unknown Error: ExtGState 'Tr0' is unknown Error: ExtGState 'Tr0' is unknown
The code is not wrong -- maybe a bit strange
works fine here with preview app or adobe reader
Also this is ok in minimals fails in minimals-beta, and I think It's legal code, but I can fail .
\newdimen\currentlayerheight \starttext \currentlayerheight=\dimexpr 12pt +0pt\relax% \the\currentlayerheight \stoptex\newdimen\currentlayerheight
current: \newdimen\currentlayerheight -> create new dimen register beta: \newdimen\currentlayerheight -> check if \currentlayerheight is already defined, it true write a message to the terminal and do nothing else create a new dimen register what did not happen here because \currentlayerheight is defined in page-lyr.tex Wolfgang
