1. If you select multiple columns, and then right click on them and select "Sort" the data table will be sorted by all selected columns.
2. You can go to the Pull Down Menus and select     Tables==>Sort    and then select whatever columns and whatever ascending/descending combination you want.
3. Below is a simple sorting script taken directly from the Scripting Index entry for "Sort"

   Names Default To Here( 1 );
   dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
   dt << Sort( By( :name ), Order( Ascending ) );

1. If you run the sort interactively
   1. Tables=>Sort
   2. Then in the resulting new data table, you right click on the "Source" entry in the Tables Panel on the upper left portion of the new data table and select "Edit"
   3. You will see the JSL that is required to do the Sort
2. Here is a cleaned up version

   Names Default To Here( 1 );
   dt = Current data table();
   dt << Sort( By( :name, :Date ), Order( Ascending, Ascending ) );

3. Also, given the example I had provided in my last entry, a guess could have been made on how to expand on it to sort 2 columns.

I strongly recommend that you take the time to read the Scripting Guide in the JMP Documentation Library.
