Do not rely on sorted order when using SAVING UNIQUE. Cite Murphy's Law.
Right now it seems "they" use an insert sort or similar to determine
uniqueness. But there's no guarantee that it will always be thus.
iirc PI correctly, that was unlikely to return a unique list if you
selected an index.
Don't ask me why, but when I read an index from BASIC using whatever the
call was to get a list of values (by necessity, obviously a list of
unique keys), it seemed to return TWO sorted lists concatenated
together.
So yes. I would never assume it to be sorted...
Cheers,
