How to export column data to string or txt

I have the following data table, how can I export the column using JSL:

1. string = 561193, 542003, 527679...

2. export the data to .txt where the values show: 561193, 542003, 527679...

Here is one way to do it

Names Default To Here( 1 );
// Create an example data table
dt = New Table( "Example",
	add rows( 100 ),
	New Column( "Number", character, set each value( Char( Random Integer( 1000, 9999 ) ) ) )
);

// Convert character column to a literal string value
string = Concat Items( dt:number[Index( 1, N Rows( dt ) )], "," );

// Write the string variable to a .txt file
Save Text File( "$TEMP/savedfile.txt", string );

@txnelson ,thank you very much for reply. it really works.

I am new JSLer. I have to seek for your help here: How can I use the selected column to replace "dt:number" in following JSL?

Names Default To Here( 1 );

dt = Current Data Table( );
// Stop the script if no open data tables
If( Is Empty( dt ), Stop());
// Make list of column names
colNames = dt << get column names();
// Select the column
nw = New Window("Column names", <<Modal,
PanelBox("Pick a column",
dtlb = ListBox(colNames, MaxSelected(1), columnSelected = (dtlb << get selected)[1] )
),
H List Box( ButtonBox("OK"), button box("Cancel"); )
);
If( nw["button"] == -1, throw() );
// Convert character column to a literal string value
inString = "'" || Concat Items( dt:number[Index( 1, N Rows( dt ) )], "','" ) || "'";

// Convert character column to a literal string value
inString = "'" || Concat Items( column(columnSelected)<<get values, "','" ) || "'";

// The above will work only if the column selected is a character column
// I suggest that you change your "<< get column names()"  to
// "<< get column names(character)"
