      When using <B

      systems, you should make sure to open the file in binary mode by
      appending a <TT

>b</TT
> to the mode used in the call to
      <A
HREF="function.fopen.html"
><B
CLASS="function"

     </P
><P
>&#13;      You are encouraged to use the <TT
CLASS="literal"
>b</TT
> flag when dealing
      with binary files, even if your system does not require it, so that
      your scripts will be more portable.
