label_len	IN:	Maximum length of label strings
	unit_len	IN:	Maximum length of unit strings
	format_len	IN:	Maximum length of format strings
	coords_len	IN:	Maximum length of coordinate system strings

	Purpose	Sets the maximum lengths for the strings that will hold labels, units, formats, and the name of the coordinate system.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	The lengths set by this routine are used by the routines DFSDgetdimstrs and DFSDgetdatastrs to determine the maximum lengths of strings that they get from the file.
		Normally, DFSDsetlengths is not needed. If it is not called, default maximum lengths of 255 are used for all strings.

	FORTRAN	integer function dsslens(label_len, unit_len, format_len, coords_len)
		integer label_len, unit_len, format_len, coords_len
