159 CHANGED: Fileio.prg
--------------------------------------------------------------------------------

     1. FReadLn() now correctly accepts a delimiter.  It also more
        closely matches the spec of C's fgets() in that the max line
        length actually read is (line length - length of delimiter).

     2. FWriteLn() is now the complement to FReadLn().

     3. FEval() was removed.

     4. FileEval() was added.  It is a text file iterator function
        that works like DBEVAL() with scoping behavior including a FOR
        and WHILE condition capability.
