/* This only works when those paramters are actually in the HTML code.
   That code for this example is :
 <APPLET CODE="ParameterExample" WIDTH=200 HEIGHT=100>
  <param name="param1" value="Hello">
  <param name="param2" value="14">
  <param name="param3" value="2">
 </APPLET>
  If you make applets for others make sure to use parameters, many
  will appreciate it.
