<title>Description</title>
<para>The <literal>load</literal> command can be used to reload in the
Scilab session variables previously saved in a file with the
<literal><link linkend="save">save</link></literal> command. If the file contains graphic handle
variables, the corresponding <link
linkend="graphics_entities">graphics_entities</link> are drawn.</para>
<para>Since Scilab 5.0, all <link linkend="uimenu">uimenu</link> or <link
linkend="uicontrol">uicontrol</link> handles are also drawn.</para>
<para><literal>load(filename)</literal> loads the variables saved in file
given by its path <literal>filename</literal>.</para>
<para><literal>load(fd)</literal> loads the variables saved in file given
by its descriptor <literal>fd</literal>.</para>
<para><literal>load(filename,'x','y')</literal> or
<literal>load(fd,'x','y')</literal> loads only variables
<literal>x,y</literal>.</para>
<para>Even if the binary file format has changed with 2.5 version of
Scilab, <literal>load(filename,...)</literal> is able to read old format
files.</para>
<para>Note that the written file is portable to other operating systems
and architectures (little and big endian).</para>
