63	\frametitle{Purpose of the User-Interface}
64	\scriptsize
65	\begin{itemize}
66	\item<2-> The standard (default) PALM code cannot account for every specific demand of a user. In order to include these specific demands, the user would have to modify the standard code.
67	\end{itemize}
68	\vspace{2mm}
69	\onslide<3->
70	\textbf{Problem:}
71	\begin{itemize}
72	\item<3-> New releases of PALM (current release is 3.10) would require the user to add his modifications to the new release again.
73	\end{itemize}
74	\vspace{3mm}
75	\onslide<4->
76	\textbf{Solution:}
77	\begin{itemize}
78	\item<4-> PALM offers a \grqq user-interface\grqq, i.e. a set of subroutines, where the user can add his modifications, and which can be re-used for future releases of the standard PALM code.
79	\item<5-> By using the user-interface, the standard code does not have to be modified by the user in most of the cases.
80	\item<6-> The user-interface subroutines are almost \grqq empty\grqq\, by default. They are called from the standard PALM code but (with some very minor exceptions) do not contain any executable code.

872	\textbf{Users can add their own (modified) user-interface to a PALM-run by carrying out the following steps:}
873	\begin{enumerate}
874	\item<2-> Copy the default (empty) user-interface files that you need (e.g. user\underline{ }module.f90, user\underline{ }parin.f90, user\underline{ }actions.f90) to a directory of your choice, e.g.:\\
875	\scriptsize
876	\par\smallskip
877	\quad \texttt{cd \~{ }/palm/current\underline{ }version}\\
878	\quad \texttt{mkdir -p USER\underline{ }CODE/example\underline{ }cbl}\\

880	\quad \texttt{cp trunk/SOURCE/user\underline{ }parin.f90\hspace{1em}USER\underline{ }CODE/example\underline{ }cbl/user\underline{ }parin.f90}\\
881	\quad \texttt{...}
882
883	\item<3-> Set an additional path in the configuration file \texttt{.mrun.config} to allow \texttt{mrun} to find and include this file:\\
884	\tiny
885	\par\smallskip
886	\scriptsize \quad \texttt{\%add\underline{ }source\underline{ }path \hspace{1em} \$base\underline{ }directory/USER\underline{ }CODE/\$fname}
887	\par\smallskip
888	\item<4-> Modify the interface routines according to your needs.
889	\item<5-> Start a PALM run by executing\\
890	\par\smallskip
891	\scriptsize \quad \texttt{mrun -d example\underline{ }cbl ...}\\
892	\par\smallskip
893	\tiny
894	The files user\underline{ }*.f90 will be automatically compiled within the job / interactive run and will replace the respective PALM default user-interface files.
895	\end{enumerate}
896	\begin{itemize}
897	\item<6-> \textbf{The modified user-interface file cannot be pre-compiled by using} \texttt{mbuild}!
898	\item<7-> The above method allows to use different user-interfaces for different runs. Just store the respective interface-files in subdirectories \texttt{USER\underline{ }CODE/abcd}, \texttt{USER\underline{ }CODE/cdef}, etc. and start \texttt{mrun} with option \grqq \texttt{-d abcd}\grqq, \grqq \texttt{-d cdef}\grqq, etc.
