<P><A NAME="idx:startupfile:56"></A><A NAME="idx:userprofilefile:57"></A><A NAME="idx:profilefile:58"></A>After 
the necessary system initialisation the system consults (see
<A NAME="idx:consult1:59"></A><A class="pred" href="consulting.html#consult/1">consult/1</A>) 
the user's startup file. The base-name of this file follows conventions 
of the operating system. On MS-Windows, it is the file
<CODE>pl.ini</CODE> and on Unix systems <CODE>.plrc</CODE>. The file is 
searched using the <A NAME="idx:filesearchpath2:60"></A><A class="pred" href="consulting.html#file_search_path/2">file_search_path/2</A> 
clauses for <CODE>user_profile</CODE>. The table below shows the default 
value for this search-path. The phrase &lt;<VAR>appdata</VAR>&gt; refers 
to the Windows CSIDL name for the folder. The actual name depends on the 
Windows language. English versions typically use
<CODE>ApplicationData</CODE>. See also <A NAME="idx:winfolder2:61"></A><A class="pred" href="system.html#win_folder/2">win_folder/2</A>

<P>After the first startup file is found it is loaded and Prolog stops 
looking for further startup files. The name of the startup file can be 
changed with the `<STRONG>-f</STRONG> <VAR>file</VAR>' option. If <VAR>File</VAR> 
denotes an absolute path, this file is loaded, otherwise the file is 
searched for using the same conventions as for the default startup file. 
Finally, if <VAR>file</VAR> is
<CODE>none</CODE>, no file is loaded.

<P>See also the <STRONG>-s</STRONG> (script) and <STRONG>-F</STRONG> 
(system-wide initialisation) in <A class="sec" href="cmdline.html">section 
2.4</A> and <A class="sec" href="initgoal.html">section 2.3</A>.
