The SUN systems store data starting with the most significant bits (<I>i.e.</I> big endian) and use IEEE floating point format while VAX's are byte swapped and have a proprietary floating point format. <P> In order to exchange data files between these systems it is necessary to use a machine independent format <I>e.g.</I> FITS. For this reason and because internal MIDAS data structures may change, it is <B>strongly</B> recommended to save data in FITS format. <P> <P> =31 =3 =1999 <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
