> Really????  How is your solution a single instruction?

Hobart,

I believe that Massimo's(who provided the solution) intention was "single
pass of data" and not truly a single "instruction".   Since OP wanted to
retain the original order of the records after eliminating the duplicates,
he needs another pass on the data, to put the data back in the original
order.

Thanks,
