+\title{A Multienumerate Package}
+\author{Dennis Kletzing\\Stetson University} \date{\today}
+\maketitle
+\begin{abstract}
+{\it The {\tt multienum.sty} package allows
+the user to produce an enumerated array of multiple
+columns, each vertically aligned on the counter. An optional
+argument provides for consecutive numbering of the array items,
+or an even-only or odd-only numbering scheme.}
+\end{abstract}
+Typesetting the solutions manual for a text frequently involves creating an
+enumerated list involving many short answers. Typically these are set with
+several items per
+line, with no attempt made to vertically align the exercise numbers. The
+{\tt multienum.sty} package provides an environment, {\tt multienumerate},
+that produces an enumerated array in which columns are vertically aligned
+on the counter. If the user wishes, the enumeration counter can
+ be changed to give a list of even-only numbers or odd-only
+ numbers.
+

+\mitemxxxx{$(2,-1,3)$}{None}{$(2,1,0,1)$}{$(0,0,0,0)$}
+\end{multienumerate}}\hrule
+\end{table}
+
+\section*{What the package does}
+Table 1 shows a typical enumerated array. The fourth entry in
+the second row is left blank since the next item is too long to
+fit in space. The third row has only two entries. To get the
+vertical alignment of the counter in column 3, we set row three
+as four entries, but left entry 2 and entry 4 blank thus
+giving more space for the first and third entries. To produce
+the enumerated array shown above, we typed the following:
+
+
+
+
+\begin{verbatim}
+ \begin{multienumerate}
+ \mitemxxxx{Not}{Linear}{Not}{Quadratic}
+ \mitemxxxo{Not}{Linear}{Not}
+ \mitemxx{$(x_1,x_2)=(2+\frac{1}{3}t,t)$ or
+ $(s,3s-6)$}{$(x_1,x_2,x_3)=(2+\frac{5}{2}s-3t,s,t)$}
+ \mitemx{$(x_1,x_2,x_3,x_4)=
+ (\frac{1}{4}+\frac{5}{4}s+\frac{3}{4}t-u,s,t,u)$
+ or $(s,t,u,\frac{1}{4}-s+\frac{5}{4}t+\frac{3}{4}u)$}
+ \mitemxxxx{$(2,-1,3)$}{None}{$(2,1,0,1)$}{$(0,0,0,0)$}
+ \end{multienumerate}
+\end{verbatim}
+The environment {\tt multienumerate} has an optional argument
+for enumerating even-only or odd-only arrays.\footnote{The
+optional arguments works only in \LaTeX2e.}
+
+\begin{itemize}
+\item \verb|\begin{multienumerate} ... \end{multienumerate}|
+\item[] produces a consecutively enumerated array
+\item \verb|\begin{multienumerate}[evenlist] ...\end{multienumerate}|
+\item[] produces an enumerated array using only even numbers
+\item \verb|\begin{multienumerate}[oddlist] ...\end{multienumerate}|
+\item[] produces an enumerated array using only odd numbers
+\end{itemize}
+
+\section*{Using the package}
+Each row of the enumerated array is set using
+one of the nine commands:
+
+\begin{small}
+\renewcommand{\arraystretch}{1.2}%1.4
+\begin{tabular}{@{}lp{3in}}
+\verb|\mitemx{}|&A single item in the row.\\
+\verb|\mitemxx{}{}|&Two items in the row.\\
+\verb|\mitemxxx{}{}{}|&Three items in the row.\\
+\verb|\mitemxox{}{}|&Three items in the row with the
+center item space left blank so the first item can extend
+into its space.\\
+\verb|\mitemxxo{}{}|&Three items in the row with the last
+item left blank so the second item can extend into
+ its space.\\
+\verb|\mitemxxxx{}{}{}{}|&Four items in the row.\\
+\verb|\mitemxoxx{}{}{}|& Four items in the row with the
+second space left blank so the first item can extend into
+its space.\\
+\verb|\mitemxxox{}{}{}|&Four items in the row with the
+third space left blank so the second item can extend into
+its space.\\
+\verb|\mitemxxxo{}{}{}|&Four items in the row with the
+last space left blank so the third item can extend into
+its space.
+\end{tabular}
+\end{small}
+
+For example, \verb|\mitemxxx{a}{b}{c}| sets three items, a, b, c equally
+spaced across the row; \verb|\mitemxox{a}{c}| sets the two
+items, a and c, across the row {\em as if\/} there were three items, leaving
+the second entry blank so that the first entry can extend into
+its space; and \verb|\mitemxxo{a}{b}| sets the two items, a and
+b, {\em as if\/} there were three items, but leaves the space
+for the third item blank, allowing the second entry to extend
+into its space.
+
+A convenient way to use the multienumerate
+package is with a two column layout using multicols. Page 7
+illustrates a typical page from a solutions manual set in
+two columns format using multicols and multienumerate.
+
+A disadvantage of the package is that the user must choose how
+to typeset each line in the array rather than letting \TeX\
+decide how to do it. This creates a lot of overhead in the
+macro since separate commands are needed for each possibility.
+It is not difficult to write a macro that will let
+ \TeX\ decide how many items to set on each line. This
+approach, while the most efficient, does not always give the
+visual appearance that the user may want.
+
+
+\section{How the package works}
+We illustrate how the package typesets a line
+containing two items. The other
+situations are similar.
+
+\noindent

+\put(205,30){\makebox(50,10)[b]{\small

+\end{picture}
+
+\bigskip
+The total width of the line is then set equal to \verb|\hsize|:
+\[\underbrace{2\texttt{$\backslash$labelwidth}+
+2\texttt{$\backslash$labelsep}}_{\texttt{$\backslash$usedxx}}+
+\texttt{$\backslash$remainxx}=\texttt{$\backslash$hsize}\]
+\[\texttt{$\backslash$remainxx}=
+\texttt{$\backslash$hsize}-
+\texttt{$\backslash$usedxx}\]
+
+\bigskip
+In this way the macro determines the width of each box
+ when two items are typeset on the line.
