Hi everyone,

What I am wanting to do, is to copy, a simple plain text file, to
another file, but omitting duplicate items.

The way I thought of doing this, involved copying all the items into a
array, and then looping through that array looking for duplicates,
removing them, and then writing to another file.

This seems a very long and drawn out way of doing this to me, and also I
do not know the initial size of the array required will be.

Could anyone suggest a effective efficient way of doing this?

Thanks
Mick
