There are options here...need to think about it for a minute.

The fundamental issue is JS/Jython/Language inside of XTCE...

We need to figure out a way for the following to be valid inside XTCE:

<AlgorithmSet>
	<CustomAlgorithm name="HelloWorld">
		<AlgorithmText language="JavaScript">
		//print("Counter" + Counter);
		NewPosition.value["Lat"] = Counter.value * 10;
		//print("NewPosition-->" + NewPosition.value);
		//print("\n");
		//print("NewPosition" + NewPosition);
		</AlgorithmText>
