#When I use the attached awk script unique on the attached data file, it 

#reports that all 4 lines of the data are the same. Using mawk it correctly 

#reports that there are no repeats.

#

#I don't know if there are limits on the size of associative array keys for the 

#purposes of reliable indexing but if there is then it is not (obviously) 

#documented.
