This package was designed with specifically -mathematics problems in mind, but can be used for other -subjects as well. The idea is to create a file containing a -large number of problems with their solutions which can be -read in by LaTeX, and then select a number of problems to -typeset. This means that once the database has been set up, -each year you can easily create a new problem sheet that is -sufficiently different from the previous year, thus -preventing the temptation of current students seeking out -the previous year's students, and checking out their -answers. There is also an option that can be passed to the -package to determine whether or not the solutions should be -printed. In this way, one file can either produce the -student's version or the teacher's version. - -<P> -<A HREF="probsoln-manual.html#top">Top</A> - -<P> - -<H1><A NAME="SECTION00030000000000000000"></A><A NAME="sec:pkgopt"></A> -<BR> -2 Package Options -</H1> -The following options may be passed to this package: -<DL> -<DT><STRONG><TT>answers</TT><A NAME="673"></A></STRONG></DT> -<DD>Show the answers -</DD> -<DT><STRONG><TT>noanswers</TT><A NAME="676"></A></STRONG></DT> -<DD>Don't show the answers (default) -</DD> -<DT><STRONG><TT>draft</TT><A NAME="679"></A></STRONG></DT> -<DD>Display the label and dataset name when a problem is used -</DD> -<DT><STRONG><TT>final</TT><A NAME="682"></A></STRONG></DT> -<DD>Don't display label and dataset name when a problem is used -</DD> -</DL> - -<P> -<A HREF="probsoln-manual.html#top">Top</A> - -<P> - -<H1><A NAME="SECTION00040000000000000000"></A><A NAME="sec:showanswers"></A> -<BR> -3 Showing and Hiding Solutions -</H1> - -<P> -In addition to the <TT>answers</TT><A NAME="688"></A> and <TT>noanswers</TT><A NAME="691"></A> package -options, it is also possible to show or suppress the solutions -using <TT>\showanswers</TT> and -<TT>\hideanswers</TT>, respectively. -The boolean variable <TT>showanswers</TT><A NAME="694"></A> determines whether the -answers should be displayed.

This package was designed with mathematics problems in +mind, but can be used for other subjects as well. The idea is to create a file +containing a large number of problems with their solutions which can be read in +by <span class="LATEX">L<span class="A">A</span><span class="TEX">T<span +class="E">E</span>X</span></span>, and then select a number of problems to typeset. This means + + + +that once the database has been set up, each year you can easily create a new +problem sheet that is sufficiently different from the previous year, thus preventing +the temptation of current students seeking out the previous year’s students, +and checking out their answers. There is also an option that can be passed to +the package to determine whether or not the solutions should be printed. In +this way, one file can either produce the student’s version or the teacher’s +version. +</p><!--l. 56--><p class="noindent" > +</p> +<!--l. 56--><p class="noindent" ><a +href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">2 </span> <a + id="x1-30002"></a>Package Options</h3> +<!--l. 57--><p class="noindent" >The following options may be passed to this package: + </p><dl class="description"><dt class="description"> +<span +class="ec-lmssbx-10">answers</span><a + id="dx1-3001"></a> </dt><dd +class="description">Show the answers + </dd><dt class="description"> +<span +class="ec-lmssbx-10">noanswers</span><a + id="dx1-3002"></a> </dt><dd +class="description">Don’t show the answers (default) + </dd><dt class="description"> +<span +class="ec-lmssbx-10">draft</span><a + id="dx1-3003"></a> </dt><dd +class="description">Display the label and dataset name when a problem is used + </dd><dt class="description"> +<span +class="ec-lmssbx-10">final</span><a + id="dx1-3004"></a> </dt><dd +class="description">Don’t display label and dataset name when a problem is used + </dd><dt class="description"> +<span +class="ec-lmssbx-10">usedefaultargs</span><a + id="dx1-3005"></a> </dt><dd +class="description">Make <span +class="ec-lmtt-10">\thisproblem</span><a + id="dx1-3006"></a> use the default arguments supplied in the + problem definition. + </dd><dt class="description"> +<span +class="ec-lmssbx-10">nousedefaultargs</span><a + id="dx1-3007"></a> </dt><dd +class="description">Make <span +class="ec-lmtt-10">\thisproblem</span><a + id="dx1-3008"></a> prompt for problem arguments (default).</dd></dl> +<!--l. 69--><p class="noindent" > +</p> +<!--l. 69--><p class="noindent" ><a +href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">3 </span> <a + id="x1-40003"></a>Showing and Hiding Solutions</h3> +<!--l. 71--><p class="noindent" >In addition to the <span +class="ec-lmss-10">answers</span><a + id="dx1-4001"></a> and <span +class="ec-lmss-10">noanswers</span><a + id="dx1-4002"></a> package options, it is also possible to show or +suppress the solutions using +</p><!--l. 74--><p class="indent" > <hr><div title="Definition"><span class="marginpar"><span +class="ec-lmtt-9">\showanswers</span><span +class="ec-lmtt-9"> </span></span><a + id="dx1-4003"></a> <span +class="ec-lmtt-10">\showanswers </span></div><hr> +</p><!--l. 76--><p class="noindent" > +and +</p><!--l. 78--><p class="indent" > <hr><div title="Definition"><span class="marginpar"><span +class="ec-lmtt-9">\hideanswers</span><span +class="ec-lmtt-9"> </span></span><a + id="dx1-4004"></a> <span +class="ec-lmtt-10">\hideanswers </span></div><hr> +</p><!--l. 80--><p class="noindent" > +respectively. +</p><!--l. 83--><p class="indent" > The boolean variable <span +class="ec-lmss-10">showanswers</span><a + id="dx1-4005"></a> determines whether the answers should be +displayed.
