Hi.

I would like to get the col name of the last data written using JSL,

Is there a solution?

Thanks.

There is a solution (or many of them). Are all of your columns numeric or can there be character columns?

Edit:

Here is one option assuming there can be character columns

Names Default To Here(1);

dt = New Table("Untitled",
	Add Rows(3),
	Compress File When Saved(1),
	New Column("Column 1", Numeric, "Continuous", Format("Best", 12), Set Values([1, ., 1])),
	New Column("Column 2", Numeric, "Continuous", Format("Best", 12), Set Values([., 2, 2])),
	New Column("Column 3", Numeric, "Continuous", Format("Best", 12), Set Values([., ., .])),
	New Column("Column 4", Numeric, "Continuous", Format("Best", 12), Set Values([., ., 3])),
	New Column("Column 5", Character, Nominal, Format("Best", 12), Set Values({"a", "", ""}))
);

newcol = dt << New Column("lastdata", Character, Nominal);
collist = dt << Get Column Names("String");

For Each Row(dt,
	m = Loc(Matrix(!IsMissing(dt[Row(), collist])));
	lastdata = Max(m);
	newcol[Row()] = collist[lastdata];
);
