Hi, I just tried out the ConTeXt standalone and found out it did not work with my gnuplot files. I have been using texlive 2011, which works fine. With the "context" command from standalone, the following error occurs, ----- Error begins ----- ! Undefined control sequence. system > tex > error on line 4 in file /Users/jin/pkgs/ConTeXt/tex/texmf-context/tex/context/base/cont-yes.mkiv: Undefined control sequence ... 1 %D \module 2 %D [ file=cont-yes, 3 %D version=2012.06.01, 4 >> %D title=\CONTEXT\ Miscellaneous Macros, 5 %D subtitle=Startup Stub, 6 %D author=Hans Hagen, 7 %D date=\currentdate, 8 %D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}] 9 %C 10 %C This module is part of the \CONTEXT\ macro||package and is 11 %C therefore copyrighted by \PRAGMA.

Please excuse me if I pasted too much. The version of context from the standalone is ConTeXt ver: 2012.06.05 09:16 MKIV fmt: 2012.6.5 int: english/english As I have mentioned, the same file works fine with context in texlive 2011, which has version ConTeXt ver: 2011.05.18 18:04 MKIV fmt: 2012.4.5 int: english/english It looks like only two weeks difference. I thought I should pass along this issue to experts on the list. Thanks, Xiao-Yong
