>> System error: The bounding indices 13 and 12 are bad for a sequence of length 12. See also: The ANSI Standard, Glossary entry for "bounding index designator" The ANSI Standard, writeup for Issue SUBSEQ-OUT-OF-BOUNDS:IS-AN-ERROR

No, this usage is wrong. ICARD assumes that data is stored as in Axiom/FriCAS database. One can not use a random string here. Axiom Book gives examples of correct usage.

ICARD does not work this way, but coercion should yield an error

The IndexCard? documentation says that bad things may happen if the original string is not of the database format.

Status: open => rejected
