/* ---------- "File I/O" ---------- */
I am trying to read various types of ascii data files into a standard common
LISP program (Ibuki Common Lisp).  There are a number of ways to create streams
and such, but how can I test for an End Of File so that my read won't return an
error?

I have gone through Steele, but apparently the appropriate function has eluded
me.  Thanks for any help.

Look at the optional arguments for READ. (page 375 of Steele).
You can specify a value for READ to return on eof.
