How to get all columns into JSL Combine Columns()?

[#1]

The question is about Combine Columns().

From Scripting index, I can find below example.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Consumer Preferences.jmp" );
dt << Combine Columns(
	delimiter( "," ),
	Columns(
		:Brush After Waking Up,
		:Brush After Meal,
		:Brush Before Sleep,
		:Brush Another Time
	),
	Selected Columns are Indicator Columns( 1 ),
	Column Name( "When to Brush" )
);

My problem is that I have random 100 columns to 200 columns of data.

How can I utilize the script to get all columns to replace above exact column name in red font?

Thanks.

Sorry for that there is no red fond in the JSL formatted script.

It's about below column's name in red font.

:Brush After Waking Up,
:Brush After Meal,
:Brush Before Sleep,
:Brush Another Time

I tried that out, see below script.

It's actually an easy one, just stuck there for a moment.

Keep trying, keep learning..

dt = current data table();
N = Ncol();
dt << Combine Columns(
	delimiter( "," ),
	Columns(
	1::N		
	),
	Selected Columns are Indicator Columns( 0 ),
	Column Name( "Combined" )
);
