Hi,
I thought I once remmebered reading about FORMAT being able to do
cardinality (or whatever that's caled), i.e.
(format nil "~<some-character>" 3)
==> "third"
Does format do that? If so, what's the directive? I looked through the
CLHS, but didn't see it there. What _was_ there was the ~R directive,
which would print "three" in the above case, but I want "third", etc.
thanks,
dave

That's ordinal.

If you read the full description of ~R, you'd see that the : modifier
does what you want.

Try "~:R" instead of "~R":
* (format t "~a ~R ~:R~%" 3 3 3)
3 three third

Note, however, if you have an older copy of lispworks, you might have
trouble with certain negative multiples of 10 (they fixed it a few
months ago):
(format nil "~:R" -90)
=> "ninetieth"
(format nil "~:R" -80)
=> "eightieth"
(format nil "~:R" -89)
=> "minus eighty-ninth"

Check out the : and @ modifiers to format control characters.
