atom_chars/2

defines a relation between an atom and a list of one-character atoms.

atom_chars(-Atom, +List)
atom_chars(+Atom, ?List)

If Atom is an atom then atom_chars/2 explodes Atom into a list of one-character atoms.
If Atom is a variable then List must be a list of one-character atoms. atom_chars/2 concatenates the characters of the list to the atom Atom.
