[NTG-context] We have a problem --- Old file no longer compiles
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:

\mathematics #1-\relax \ifmmode #1

$
?
The point in the source that seems to cause the difficulty is:
\noindent In \in{Exercises}[ex:secqu.9]-\in[ex:secqu.16],
convert the given decimal to a fraction.
% Exercise #9
\beginquestion
\startquestion[ex:secqu.9]
$0.648$
\stopquestion
\endquestion
\beginlonganswer
\startanswer
There are three decimal places, so
$0.648=\frac{648}{1000}=\frac{81}{125}$.
\stopanswer
\endlonganswer
\beginshortanswer
\startanswer
$\displaystyle \frac{81}{125}$
\stopanswer
\endshortanswer
Shortanswer and longanswer are blocks. 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?

Re: [NTG-context] We have a problem --- Old file no longer compiles
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.

mpgraph.1)

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.

Re: [NTG-context] We have a problem --- Old file no longer compiles
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.

Re: [NTG-context] We have a problem --- Old file no longer compiles
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]
