</h3>
<p>
<a name="1206181"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The command <font size=2 face=Courier><strong>fread</strong></font> reads values from the file <font size=2 face=Courier><strong><em>filename</em></strong></font> into a variable. If the <font size=2 face=Courier><strong>fread</strong></font> command is the first file operation on the file then it is opened for reading. Subsequent <font size=2 face=Courier><strong>fread</strong></font> commands to <font size=2 face=Courier><strong><em>filename</em></strong></font> read the next line in the file; the file is only closed when an <font size=2 face=Courier><strong>fclose</strong></font> command is called on the <font size=2 face=Courier><strong><em>filename</em></strong></font>.</font>
