Same as any other sequence: copy-sequence

it's not immutable, but it's not stretchy either.

<string> is a superclass. <byte-string> and <unicode-string> are
subclasses that hold different sized characters.

No problem.  All newbie quesitons are very welcome!  Feel free to ask
anything either here or else on the channel.  I just noticed you on
the channel 18 minutes after you arrived, but unfortunately 7 minutes
after you left.  People are usually around, but may not notice for a
while, so it's best to stay logged in while waiting if you can.

Regards,
Bruce
