>>seems, to me a lot easier than this checksum manipulation, besides sys(2017), I believe constructs a checksum with aid of your pc's time(miliseconds) so likely two or more fields with repeated values will receive different checksums, should need some testing to confirm this.

Dragan,

you are correct both sys(2007) and sys(2017) calculate a checksum without clock.
Still I believe to perform a SQL select to find duplicats would be more handy than to manipulate with checksums.
