Is it strictly legal to have a call to FORMAT such as:

   (format t "foo" 1)

?

I suspect it probably is, but I couldn't find a statement either way.

Thanks]

22.3.3 of Steele says "It is an error if no argument remains for a
directive requiring an argument, but is not an error if one or more
arguments remain unprocessed by a directive."

Sounds legal to me.

The HyperSpec agrees, too:

# 22.3.10.2 Missing and Additional FORMAT Arguments
#
# The consequences are undefined if no arg remains for a directive
# requiring an argument. However, it is permissible for one or more
# args to remain unprocessed by a directive; such args are ignored.
