% \begin{abstract}
% Address files are not only of interest for letters using the \KOMAScript{}
% class \cls*{scrlttr2} or the \KOMAScript{} package \pkg*{scrletter}. Other
% applications such as the creation of address books or telephone directories
% are also quite common. In addition, it can also be useful to access not only
% the addressee's record in a letter, but also other records in an address
% file. This is exactly the task of the \pkg*{scraddr} package.
% \end{abstract}
% \tableofcontents
%
% \section{User Manual}
%
% You can find the user manual of \pkg*{scraddr} in the \KOMAScript{} manual,
% either the German \file{scrguide-de.pdf} or the English
% \file{scrguide-en.pdf}.

% \subsection{Options}
%
% Preliminary note: \pkg*{scraddr} is a very, very old package from the early
% days of \KOMAScript. Therefore it does not support \emph{key=value} options
% as other \KOMAScript{} packages do.
%
% \begin{option}{adrFreeIVempty}
% \changes{v1.1a}{2002/05/19}{new}
% \begin{option}{adrFreeIVshow}
% \changes{v1.1a}{2002/05/19}{new}

% \changes{v1.1a}{2002/05/19}{new}
% \begin{macro}{\@adrFIVerror}
% \changes{v1.1a}{2002/05/19}{new}
% The options allow the choice whether \cs{FreeIV}, defined by \cs{adrentry},
% should be ignored, output, result in a warning or an error message. Default
% is \opt{adrFreeIVshow}. The selected choice is stored as a number in
% \cs{@adrFIVerror} (0 = \opt{adrFreeIVempty}, 1 = \opt{adrFreeIVshow},
% 2 = \opt{adrFreewarn}, 3 = \opt{adrFreeIVstop}). Unknown values should
% be handled as \opt{adrFreeIVstop} too, but are not recommended.

% \subsection{Using an element of an address file}
%
% Selecting the elements by names instead of cryptic macros, could be
% easier. So we use well named macros for the selection. All these macros have
% exactly one mandatory argument: the \meta{shortcut} which is argument 8 of
% \cs{adrentry} resp. argument 9 of \cs{addrentry} in the address file.
%
% \begin{command}{\Name}
% The \cs{Name} is a combination of \cs{Firstname} and \cs{Lastname} with a
% normal word separator space in between.
%    \begin{macrocode}
\newcommand*{\Name}[1]{\FirstName{#1}\ \LastName{#1}}
%    \end{macrocode}
% \end{command}
% \begin{command}{\FirstName}
