Re: Unformatted File IO


The contents of test.txt are as you state below.
/*check to see that the file is there*/

(*open a file handle to the file (handle), read in the contents line by 
line (RecordSeparator) as words separated by any of the possible 
separators (WordSeparators) *)

(*note the "\"" in the list of WordSeprators is intentional because of 
your double quoted strings*)

handle = OpenRead["test.txt"];
z = ToExpression[
     ReadList[handle, Word, RecordSeparators -> {"\n"},
       WordSeparators -> {" ", "\t", "\""}, RecordLists -> True]
