TOP. Commentary Note -- Token

Token.
Token is a transformation of ideas that produces
a character-facsimile of its argument idea-form,
meanwhile leaving the argument structure intact.
Given an idea that refers to an existing form,
it constructs an initialized cog-type structure
that has the same character in its 'sign' field
as that of the indicated form.
