Hello fellow lisp hackers,

I am reading data from a file of unspecified length using with-open-file and a
do loop.  Is there a keyword I can specify which will redirect errors?  Right
now I get the expected end of file error.  What do I do?

Thanks

(read ..) takes optional arguments on what to do about end-of-file errors; 
(read <your-path> nil 'endfile)  will return the symbol 'endfile when eof is
encountered, and you can handle that within your code.  RTFM, as they say :-)
