<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />Does someone know what is the script command for collapsing uncollapsing the head title?
This is the default:

I would like to feel free if i would like this result as final (sometimes too much outputs to scroll through)

Thanks all in advance
Here's an example that will do what you want. You need to convert the tabulation to a report and then you can send messages to the first outline box, which will collapse the head title.
dt = open("$sample_data\Car Physical Data.jmp");
dtab = dt << Tabulate(
Show Control Panel( 0 ),
Add Table(
Column Table( Analysis Columns( :Weight ), Statistics( Mean ) ),
Column Table( Analysis Columns( :Turning Circle ), Statistics( Mean ) ),
Column Table( Analysis Columns( :Displacement ), Statistics( Mean ) ),
Column Table( Analysis Columns( :Horsepower ), Statistics( Mean ) ),
Column Table( Analysis Columns( :Gas Tank Size ), Statistics( Mean ) ),
Row Table( Grouping Columns( :Country, :Type ) )
)
);
dt_report = report(dtab);
dt_report[outline box(1)] << close(1);
