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 Usage and Reference Version 6
