After spending an hour or two trying to get AssignPresetName script to work with MoI4 and MoI5beta, I finally downloaded Pilou's French version, which worked just fine.
Then the versions I had struggled with, starting working. I wonder if there is some sort of Caching going on with my computer? I also think that Microsoft oneDrive perhaps should not be used while working on scripts? There is a several minute delay between work and home computers updating saved script versions.
Yesterday I had to replace the cmos battery in the computer at home. The clock kept stopping, and files were back-time dated, at home. And once, the improper time prevented logon to MoI forum.

Next came naming an object in a script.

Name that point, (and style it RED):

function CreatePoint( xValue, yValue, zValue, ptName )
{
	var pt = moi.vectorMath.createPoint( xValue, yValue, zValue );
	var factory = moi.command.createFactory( 'point' );
	factory.setInput( 0, pt );
	var ptObj = factory.calculate();
	if ( !ptObj )
		return false;
	ptObj.setProperty( 'name', ptName ); // Name the point.	
	var point = ptObj.item(0);

var g_style_index = 1;// This Style MAY be red.	
point.styleIndex = g_style_index;
// All the points created ended up Style RED.  	
	
	return point;
}

	// Create pointA
	var xValue = 1;
	var yValue = 2;
	var zValue = 0;
	var ptName = 'pointA';
	var pointA = CreatePoint( xValue, yValue, zValue, ptName );
	moi.geometryDatabase.addObject( pointA );

The Style code was just a lark, and different Styles could be fed to the subroutine function.

I suppose there is some way to script assigning an object to a group...
