+!            This program creates two files, copy1.h5, and copy2.h5. 
+!            In copy1.h5, it creates a 3x4 dataset called 'Copy1',   
+!            and write 0's to this dataset.                         
+!            In copy2.h5, it create a 3x4 dataset called 'Copy2',    
+!            and write 1's to this dataset.                          
+!            It closes both files, reopens both files, selects two   
+!            points in copy1.h5 and writes values to them.  Then it  
+!            uses an H5Scopy to write the same selection to copy2.h5. 
+!            Program reopens the files, and reads and prints the contents of 
+!            the two datasets.
