Dear all
I have to sort a file with 650,000 records in search of duplicate
records.. and I need a list of duplicates (not a list without
duplicates)...
indexS=sort(testTotal)
test=testTotal[indexS]
indexU=uniq(test)

indexU is an index with no duplicates..
how do I get an index pertaining to the duplicates only?..
please help..
thanks in advance
dilkushi
