Usually 1.  The first thing is look up the word in the dictionary.  If
not, see if it's an integer literal, etc.  That's what the text
interpreter does now.

It runs a user-supplied function.  You could read the spec.  Disclosure:
I've looked at the spec but not really studied it yet, so I don't
understand all of it.
