	    IDL uses XDR for Save/Restore files, and for files opened
        with the XDR keyword to OPENR, OPENW, and OPENU.
	IDL 3.0.0 has a bug that affects users of the DECstation.
	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 other than 3.0.0
	have this bug corrected, meaning that older double precision
	data saved on one of these machines cannot be restored using
	a different 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.
