	    IDL uses XDR for Save/Restore files, and for files opened
        with the XDR keyword to OPENR, OPENW, and OPENU.
	IDL 2.4.0 and earlier has a bug that affects users of 
	big-endian MIPS cpu based machines (SGI and MIPS, but not
	DecStations). On these systems, all XDR output of double
	precision floating point data has its least and most significant
	longwords reversed. This presents no problem as long as such
	files are only used on these machines. However, XDR files with
	double precision data cannot be moved between these machines
	and others without the need to correct the data.

	To further complicate matters, IDL versions later than 2.4.0
	have this bug corrected, meaning that older double precision
	data saved on one of these machines cannot be restored using
	a newer version of IDL without the need to correct the data.

	The user library procedure MIPSEB_DBLFIXUP can be used to
	repair any double precision floating point data affected
	by this problem.
