-Introduction</A>
-</H1>
-The <TT>probsoln</TT> package is designed for teachers or
-lecturers who want to create problem sheets for their
-students. 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 L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X, 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.

-can be used later. The argument <I>problem</I> is normal
-L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X code that should be used to typeset the problem.
-The argument <I>solution</I> is normal L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X code that
-should be used to typeset the solution, if required. For
-example, the following defines a problem with the label
-<A NAME="quaddiff"></A><TT>quaddiff</TT>:

-The optional argument <I>nargs</I> specifies the number of

-Suppose all the above problems are defined in the file

-\documentclass{article}

-\usepackage{probsoln}
-\input{probs}
-
-\begin{document}
-Differentiate the following functions with respect to $x$:
-\begin{enumerate}

-\item \useproblem{diff:quad}{2}{3}{1}
-\item \useproblem{diff:quad}{0}{1}{2}
-\end{enumerate}
-\end{document}

-The answer sheet can then be generated by passing the option
-<TT>answers</TT> to the <TT>probsoln</TT> package.

-Selecting All Problems</A>
-</H1>
-
-<P>
-To select all problems defined in a database, in the order in
-which they were defined, use the command:
-
-<A NAME="selectallproblems"></A><TT>&#92;selectallproblems</TT><A NAME="447"></A><code>{</code><I>filename</I><code>}</code>
-For example, suppose the problems are defined in the file

-which uses all these problems:
-<PRE>
-\documentclass[a4paper]{article}
-
-\usepackage{probsoln}

-
-<A NAME="selectrandomly"></A><TT>&#92;selectrandomly</TT><A NAME="452"></A><code>{</code><I>filename</I><code>}{</code><I>n</I><code>}</code>
-<BR>
-<BR>
-The command <TT>&#92;selectrandomly</TT><A NAME="456"></A> will select <I>n</I>
-problems that are defined in the file <I>filename</I>. Each
-problem is proceeded by
-<A NAME="PSitem"></A><TT>&#92;PSitem</TT><A NAME="461"></A> which is
-defined to be <TT>&#92;item</TT><A NAME="465"></A>, so the command
-<TT>&#92;selectrandomly</TT><A NAME="469"></A> should occur within one of the
-list-like environments, such as <TT>enumerate</TT>.
-For example:
-<PRE>
-\begin{enumerate}
-\selectrandomly{easy.tex}{4}
-\end{enumerate}
-</PRE>
-will result in four numbered problems, selected at random
-from the file <TT>easy.tex</TT>. (The <TT>.tex</TT> extension
-may be omitted.) Each problem is followed by the command
-<A NAME="endPSNitem"></A><TT>&#92;endPSNitem</TT><A NAME="474"></A> which by default does nothing.
-
-<P>
-Multiple <TT>&#92;selectrandomly</TT><A NAME="478"></A> commands may be used, however a
-different file must be used each time. For
-example:
-<PRE>
-\begin{enumerate}
-\item Differentiate the following functions with respect to $x$:
-
-\begin{enumerate}
-\selectrandomly{samples/easy.tex}{3}
-\selectrandomly{samples/args.tex}{1}
-\end{enumerate}
-
-\selectrandomly{samples/implicit.tex}{1}
-\selectrandomly{samples/1stprncpl.tex}{1}
-
-\end{enumerate}
-</PRE>
-This will result in a total of 6 problems, numbered 1(a),
-1(b), 1(c), 1(d), 2 and 3.
-
-<P>
-If a randomly selected problem requires arguments, a message
-similar to the following will be displayed:
-<PRE>
-Problem diff:quad requires 3 argument(s), please specify (e.g. {5}{3}):
-</PRE>
-Enter the required arguments, where each argument is
-enclosed in braces ({ }).

-</H1>
-
-The command <A NAME="PSNrandseed"></A><TT>&#92;PSNrandseed</TT><A NAME="483"></A><code>{</code><I>n</I><code>}</code> specifies
-the seed for the random number generator. For example,
-if you are using <A HREF="#selectrandomly"><TT>&#92;selectrandomly</TT><A NAME="489"></A></A>,
-<code>\PSNrandseed{\year}</code> will produce a different set of
-problems each year, whereas <code>\PSNrandseed{\time}</code>
-will produce a different set of problems each time you
-L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X the problem sheet (as long as you leave at least a
-minute between runs.)
-
-<P>
-The command <A NAME="random"></A><TT>&#92;random</TT><A NAME="494"></A><code>{</code><I>counter</I><code>}{</code><I>a</I><code>}{</code><I>b</I><code>}</code>
-generates a random number from <I>a</I> to <I>b</I> and
-stores it in the L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X counter <I>counter</I>. For example,
-to select 2, 3 or 4 problems from the file
-<TT>implicit.tex</TT>:
-<PRE>
-\newcounter{numproblems}
-\begin{enumerate}
-\random{numproblems}{2}{4}
-\selectrandomly{implicit.tex}{\value{numproblems}}
-\end{enumerate}
-</PRE>
-(Note the use of <TT>&#92;value</TT><A NAME="498"></A>.)
-
-<P>
-This command can also be used to generate random values for
-problems that take arguments. Consider the problem <A HREF="#diff:quad"><TT>diff:quad</TT></A>
-defined earlier. Three counters can be defined to represent the
-three coefficients:
-<PRE>
-\newcounter{A}
-\newcounter{B}
-\newcounter{C}
-</PRE>
-Random values can now be assigned to these counters:
-<PRE>
-\random{A}{-5}{5}
-\random{B}{-5}{5}
-\random{C}{-5}{5}
-</PRE>
-Finally, the problem can be used (note the use of <TT>&#92;arabic</TT><A NAME="505"></A>):
-<PRE>
-\useproblem{diff:quad}{\arabic{A}}{\arabic{B}}{\arabic{C}}
-</PRE>
-
-<P>
-The command
-<A NAME="doforrandN"></A><TT>&#92;doforrandN</TT><A NAME="510"></A><code>{</code><I>n</I><code>}{</code><I>cmd</I><code>}{</code><I>list</I><code>}{</code><I>text</I><code>}</code> will apply
-<I>text</I> for a random selection of <I>n</I> items in the
-comma separated <I>list</I>. In each iteration the list
-item is denoted by <I>cmd</I>. For example, suppose you
-have three files called <TT>file1.tex</TT>,
-<TT>file2.tex</TT> and <TT>file3.tex</TT>, and you want to
-select 1 problem from two of the three files, then you can
-do:
-<PRE>
-\doforrandN{2}{\file}{file1,file2,file3}{\selectrandomly{\file}{1}}
-</PRE>
-Note that it is also possible to do
-<PRE>
-\newcounter{numproblems}
-\random{numproblems}{1}{3}
-\selectrandomly{file\arabic{numproblems}}{1}
-\random{numproblems}{1}{3}
-\selectrandomly{file\arabic{numproblems}}{1}
-</PRE>
-however there is a possibility that the same file may be
-selected twice which will cause an error.
-
-<P>
-The command <A NAME="showanswers"></A><TT>&#92;showanswers</TT><A NAME="515"></A> will show the solutions from
-that point on. May be localised by placing within a group.
-
-<P>
-The command <A NAME="hideanswers"></A><TT>&#92;hideanswers</TT><A NAME="520"></A> will hide the solutions from
-that point on. May be localised by placing within a group.
-
-<P>
-The solution is placed inside the solution<TT>solution</TT>
-environment. By default this environment simply does
-<code>\paragraph{\solutionname:}</code> at the start, where
-<A NAME="solutionname"></A><TT>&#92;solutionname</TT><A NAME="526"></A>
-has the value: Solution. See the file <TT>sample3.tex</TT>, which
-comes with this package, for an illustration of how to
-customise the way in which the randomly selected problems are
-displayed. This sample file randomly selects multiple choice
-problems stored in the file <TT>tabmchoice.tex</TT>, and displays them
-in a longtable <TT>environment</TT>.
-
-<P>
-The boolean variable <TT>showanswers</TT> is defined to be
-true if the answers are shown and false otherwise. You can
-therefore do something like:
-<PRE>
-\ifthenelse{\boolean{showanswers}}{\textbf{Solution Sheet}}{}
-</PRE>
-and <B>Solution Sheet</B> will be printed only if the
-answers are displayed. (For more information on
-<TT>&#92;ifthenelse</TT><A NAME="531"></A> and <TT>&#92;boolean</TT><A NAME="535"></A> see the
-documentation for the <TT>ifthen</TT> package by
-David Carlisle.)
-
-<P>
-The <TT>showanswers</TT> switch can also be used within the definition
-of a problem, if you want the question to appear differently if the
-solution is displayed. For example:
-<PRE>
-\newproblem{mc:prod}{%
-Which of the following is the derivative of $x\sin(x)$?
-(Circle the correct answer.)
-\ifthenelse{\boolean{showanswers}}{}%
-{\begin{description}

-\item[C] $\sin(x) + x\cos(x)$

-}}{%
-\begin{description}
-\item[A] $\sin(x)$
-\item[B] $x\cos(x)$
-\item[\textcircled{C}] $\sin(x) + x\cos(x)$ (product rule).
-\end{description}
