Hi, Something is wrong with \typefile in latest context in MKIV. \starttext \typefile{somefile} \stoptext (the file 'somefile' should exist) gives ! Undefined control sequence. <argument> \filepath \pathplusfile #1#2->#1 \f!pathseparator #2 \mktypefileverbatim ...rs.typefile("\readfilename ")} \dosometyping ...rt }{\typingparameter \c!stop }}} \stopverbatimcolor \stoppa... \dotypefile ...else \dodotypefile [\v!file ][]{#3} \fi \fi l.3 \typefile{somefile} Also, in MKII, when the file does not exist, you get a warning message in the pdf output. In MKIV, there is no warning. Missing files are silently ignored. Aditya
