Hi context users ! I want to test the presentations modules of context, because are very nice. I am testing module pre-05 (fuzzy), i am using the code at the end of the archive: %% code example.tex ----------> \usemodule[pre-05] \starttext \TitlePage{Title Page\\pre-fuzzy} \Topics{Some Nice Quotes} \Topic{A Few} \Subject{Knuth} \input knuth \Subject{Tufte} \input tufte \Topic{Some More} \Subject{Zapf} \input zapf \Subject{Bryson} \input bryson \stoptext %% endcode -------------> But this code not run: the command texexec example.tex says: %% --------> ! Missing number, treated as zero. <to be read again> \endcsname \@@amvbox ... -\pagebackgroundvoffset +\endcsname \c!topoffset \relax \box \... <argument> ...ght\c!left }\interactionmenu [right] \getvalue {\??am right\c!r... \firstofoneargument #1->#1 \next2 #1,->\docommand {#1} \doprocesscommaitem \doprocesscommalist ...item \gobbleoneargument #1, ]\relax \global \advance \... ... l.10 \Subject{Knuth} \input knuth ? h A number should have been here; I inserted `0'. (If you can't figure out why I needed to see a number, look up `weird error' in the index to The TeXbook.) %% --------> I don'n know what is the problem because the example code is from the archive s-pre-05. Thanks in advance for your answers. Hector
