How can quickly add data to save table?

Question

For example "Big Class.jmp" is made into two tables:"Big Class1"、"Big Class2", and the data in the two tables is repeated.
Save the table in "Big Class1".

How can add the data from "Big Class2" to "Big Class1" using the JSL implementation?

Compare the data in "Big Class2".Implement the existing name rows in "Big Class1" and update the data.
"Big Class1" does not have a name row, will "Big Class2" new name increment "Big Class1" data.This makes the data in "Big Class1" 40 rows.

Does JMP have a ready-made command?

Thanks Experts!

dt=Open("$SAMPLE_DATA/Big Class.jmp");
dt<<Select Where(row()<22);d1=dt<<Subset(Output Table("Big Class1"),Selected Rows(1),selected columns(0));

dt<<Select Where(row()>13);d2=dt<<Subset(Output Table("Big Class2"),Selected Rows(1),selected columns(0));

d1<<Update(With(d2));？？

Once you know the JSL keyword, do 'Help > Scripting Index' to find out how to use it.

NamesDefaultToHere(1);

// Get a table
dt1 = Open("$SAMPLE_DATA/Big Class.jmp");

// Make a second table (that happens to be identical)
dt2 = Eval(dt1 << getScript);

// Concatenate the second table to the first
dt1 << Concatenate(DataTable(dt2), AppendToFirstTable);
Close(dt2, NoSave);

// Delete duplicate rows
Wait(2);
dt1 << selectDuplicateRows;
dt1 << deleteRows;

* How is the JSL encoded for this operation?

very thankful
