Hi, Using the following code \useMPlibrary[txt] \startMPpage graphictext "FOO"; \stopMPpage results in ! Undefined control sequence. \douseMPlibrary ...stprefix #1}\makeshortfilename [\truefilename {\f!metapos... \next1 #1,->\douseMPlibrary {#1} \doprocesscommaitem \doprocesscommalist ...item \gobbleoneargument #1, ]\relax \global \advance \... l.1 \useMPlibrary[txt] ? This used to work (latest pdf is from 30.11.2010), but the macro \makeshortfilename is no longer defined in the latest beta (meta-ini.mkiv, line 853). Anyhow, I used an older backup of my tex tree to get around this. Peter
