Very nice! Simple, handles lists with long list of duplicates easily and correctly.

There is a TIP "shorter list first in FilterValues()", so changing parameter order in FilterValues() would make it a bit faster generally.

Hi,

With all his years, I'm not looking for speed any more in Filemaker.
But you're right to point it out
In fact, if we want to optimize the code, we must put a Let for each calculation is the fastest :
let ([
Prepa = Substitute ( Out & ¶ ; [¶ ; Char (8203 ) & ¶]) ;
Unic = UniqueValues ( Prepa & MyList )
];
FilterValues ( Unic ; MyList )
)

Merci à tous, ravie que ce calcul vous interpelle !

This seems to add a pilcrow (line break) to the end of the result which needs to be removed (by stripping off the final character).

Hello,
yes, absolutely.
it was a choice, since all the native functions ( filterValues, LeftValues, middleValues etc ) of filemaker which deal with the lists add an "¶" at the end
Thanks you

Chiming in very late here -- that's not correct. FilterValues is considerably faster when you put the longer list first, as per https://filemakerhacks.com/2020/05/16/filtervalues/
