Yes. IML has three subroutines for handling splines:
SPLINE Call evaluates points on the spline
returns a matrix containing fitted values
SPLINEC Call evaluates points on the spline
returns matrices containing coefficients and endpoint slopes
SPLINEV Function evaluates points on a spline
returns a matrix with fitted values
See the documentation on SAS/IML* Software
