EX1

// This is a self contained sample program for the function sort, 
// Its sample data with a back-up is created at the beginning of the program. 
// To run the program, enter the following command in the Script window:
//   sort_ex1
// This will return the sorted datasets (A and B), and give the following message:
//   Sorting Data8_A (as X) for Data8_B (as Y) succedded.
