Hi Dick,
At the start of this thread, it was observed that comparison of arrays
as suggested by the documentation may detect false positives.
Keys of arrays are sorted when they are used by a function or a get or
put command. The sort is not random, as I stated before. Therefore, the
arrays must be equal.
I don´t know if the hash is created before or after the sort, so I can´t
comment on that. We´ll be able read the source code soon and then we all
can know this kind of things.

As you can conclude from
"To compare two arrays, simply use the = operator directly on them rather than
encoding them first."
the documenation, particularly with regard to arrays, is not always correct.
Hi, Mark.
Of course documentation isn't always correct, but I don't see how to conclude
that from that sentence. In my experience, that sentence has been correct.
What's incorrect about it?
Moreover, I would expect that computers return the same value when doing two
equal calculations in the same way under equal circumstances.
ArrayEncode encodes not only the keys and values we can see in the array but
also the hash keys we cannot see. The invisible hash keys depend in part on
the sequence in which the keys were added to the array, so they may be
different for two equal arrays, so the encodings may be different too.
At least, that's what I remember reading somewhere. Sorry, I don't remember
where.
