dim	IN:	Dimension this label, unit and format refer to
	label	IN:	Label that describes this dimension
	unit	IN:	Unit to be used with this dimension
	format	IN:	Format to be used to display scale

	Purpose	Sets the label, unit, and format strings corresponding to the specified dimension.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	In both FORTRAN-77 and C programs, dim = 1 for the first dimension, and dim = 2 for the second dimension. If the user is not interested in one or more strings, empty strings can be used as parameters for the DFSDsetdimstrs call. For example, DFSDsetdimstrs(1, "vertical", " ", " ") will set the label for the first dimension to "vertical" and set the unit and format to empty strings.

	FORTRAN	integer function dssdist(dim, label, unit, format)

		character*(*) label, unit, format
