\section{Creating Math Names}

The program automatically recognizes a special set of multicharacter names,
including many common mathematical functions, as you type them. You can also
create multicharacter math names for use in mathematics.

For example, you can create the names Force, Mass and Acceleration, and
assign a value to Mass and Acceleration. Then, you can use the math names to
write the equation

\begin{center}
$\func{Force}=\func{Mass}\times \func{Acceleration}$
\end{center}

and compute the value of Force. If you haven't defined the words as
multicharacter variable names before you type them in mathematics, the
program considers each letter in each word to be a variable.

The program recognizes the math names listed in the \hyperref{Automatic
Substitution}{}{}{Auto_sub.tex} dialog box when you type them if the
insertion point is in mathematics and the Disable automatic substitution
checkbox in the Automatic Substitution dialog box is unchecked. \medskip

\subsubsection{$\blacktriangleright $\quad To create a math name}

\begin{enumerate}
\item  Click\FRAME{itbpF}{22.4375pt}{21.0625pt}{2pt}{}{}{function.wmf}{%
\special{language "Scientific Word";type "GRAPHIC";maintain-aspect-ratio
TRUE;display "PICT";valid_file "F";width 22.4375pt;height 21.0625pt;depth

"XNPEU";}}, or from the Insert menu, choose Math Name.

\item  In the Name box, type the math name.

\item  In the Name Type area, select Operator or Function.

\item  If the math name is an operator that carries limits, set the
placement of the \hyperref{limits}{}{}{Limit.tex}.

\item  Choose Add.

\item  Choose OK.\medskip
\end{enumerate}

\subsubsection{$\blacktriangleright $\quad To define the math name as a new
automatic substitution sequence}

\begin{enumerate}
\item  From the Tools menu, choose Automatic Substitution.

\item  In the Keystrokes box, type the substitution sequence using numeric
and alphabetic characters only.

\item  Place the insertion point in the Substitution box.

\item  Click\FRAME{itbpF}{22.4375pt}{21.0625pt}{2pt}{}{}{function.wmf}{%
\special{language "Scientific Word";type "GRAPHIC";maintain-aspect-ratio
TRUE;display "PICT";valid_file "F";width 22.4375pt;height 21.0625pt;depth

"1";cropright "1";cropbottom "0";filename 'Function.wmf';file-properties
"XNPEU";}}, or from the Insert menu, choose Math Name.

\item  Select the new math name, and choose OK.

\item  Choose OK to return to your document.\medskip
\end{enumerate}

Now, when you type the math name while the insertion point is in
mathematics, the program inserts the math name directly into your document
at the insertion point. If you use the Math Name button or the command, the
program displays the Math Name dialog box so that you can select the math
name you want.\medskip
