Hi, In setting out to update our intermediate algebra textbook for the fall semester (http://msenux.redwoods.edu/IntAlgText/), I've found that a file that would formerly compile under a previous version of context will no longer compile. Preliminaries $ ctxtools --contextversion CtxTools | context version: 2007.06.06 09:53 (/usr/local/gwTeX/ texmf.local/tex/context/base/context.tex) CtxTools | context version: 2007.06.06 09:53 (/usr/local/gwTeX/ texmf.local/tex/context/base/cont-new.tex) Preliminaries $ texmfstart texexec --version TeXExec | version 6.2.0 - 1997-2006 - PRAGMA ADE/POD The error message I receive is: textblocks : reading blocks from NumberSystemsExercises.tub (./NumberSystemsExercises.tub textblocks : shortanswer loaded and typeset textblocks : shortanswer loaded and processed textblocks : shortanswer loaded and typeset textblocks : shortanswer loaded and processed textblocks : shortanswer loaded and typeset textblocks : shortanswer loaded and processed textblocks : shortanswer loaded and typeset textblocks : shortanswer loaded and processed textblocks : shortanswer loaded and typeset !

Startanswer is an enumeration. I've tried this in other files and gotten similar errors, which seem to be tied to the frac command. Can anyone help?
Here is another example, this time not within a block, but within an enumeration again: The source: \startproperty Let $a$ and $b$ be any numbers such that $a=b$. Then, if $c$ is any number other than zero, \placeformula[-] \startformula ac=bc.\index{equations+multiplication} \stopformula If $c$ is any number other than zero, then \placeformula[-] \startformula \frac ac=\frac bc.\index{equations+division} \stopformula \stopproperty Where property is defined: \defineframedtext[MyBox] \definemeasure[BoxWidth][\textwidth] \defineblank[BoxBlank][medium] \setupframedtexts [MyBox] [width=\measure{BoxWidth}, before={\blank[BoxBlank]}, after={\blank[BoxBlank]}, background=color, frame=no, location=middle] \setuplabeltext[property=Property] \defineenumeration [Default] [location=serried, width=broad, text=\labeltext{}, headstyle=bold, inbetween=\blank, before=\blank, after=\blank, way=bysection, sectionnumber=no, number=yes, right=.] \defineenumeration [property] [Default] [text=\labeltext{property}, before={\startMyBox[backgroundcolor=lavender]}, after=\stopMyBox, way=bysection, sectionnumber=no] And the error. Again, the \frac command seems to be the culprit. (./EquationsSection.tuo) [1.15] [MP to PDF] (./EquationsSection- mpgraph.1) [2.16] [3.17] !

The newmat module seems to be the culprit. After loading newmat add \unexpanded\def\frac#1#2{\mathematics{\genfrac{}{}{}\donothing{#1}{#2}}} and it should work fine. I do not really understand why this is failing. Aditya

Ok. The third argument of \genfrac should be {} and not \empty, otherwise \ifx @#3@ in \genfrac evaluates to false. So, either we need to change \ifx @#3@ to something more robust, or revert back to older definitions of (d|t)frac. Aditya
Aditya, Thanks for the reply. As far as I know, we don't explicitly import newmat in our environment files: trunk $ grep usemodule * bookenv-clean1-base.tex:\usemodule[math-ext] bookenv-clean1-colors.tex:\usemodule[colors] As you can see, we do use the module math-ext.

Aditya,
Thanks for the reply. As far as I know, we don't explicitly import newmat in our environment files:
trunk $ grep usemodule * bookenv-clean1-base.tex:\usemodule[math-ext] bookenv-clean1-colors.tex:\usemodule[colors]
As you can see, we do use the module math-ext
Firstly, you do not use to explicitly use math-ext. AFAIU, it is included automatically. Secondly, something in your setup is including newmat, because \dogenfrac is defined in newmat. Look into the log file or the tui file for newmat. If newmat is not being loaded, then something strange is happening. Aditya
Yes, it is getting loaded: system : module newmat loaded Turns out it's not in our style files, but in the exercise file that I am compiling: \startcomponent NumberSystemsExercises \project book \product Preliminaries/PreliminariesChapter \usemodule[newmat] \usemodule[math-ext] \usemodule[fig-base] \usefigurebase[figures/figlibNumberSystemsExercises] On Jul 4, 2007, at 10:02 PM, Aditya Mahajan wrote:
