Hi, when you use the \setupMPgraphics command in a document, e.g. \setupMPgraphics[] \starttext \stoptext the following error message appears: lua error > error on line 1 in file /Users/wolf/TeX/test.tex: [\directlua]:1: decimal escape too large near '\457‘ The reason for this is the use of \directMPgraphicsparameter which expands to \relax in the following block (can be found at the end of meta-ini.mkiv): \appendtoks \edef\p_mpy{\directMPgraphicsparameter{mpy}}% \ifx\p_mpy\empty \else \let\MPdataMPYfile\p_mpy \ctxlua{metapost.makempy.registerfile("\p_mpy")}% \fi \to \everysetupMPgraphics Wolfgang
