我用了这个编程想打开2007 Survey of Consumer Finances的Survey Data

LIBNAME OUT 'd:\scf';
FILENAME scf2007 'D:\SCF\scf2007';
PROC CIMPORT DATA=OUT.dataset INFILE=scf2007;
RUN;

可在他日志log上显示说

LIBNAME OUT 'd:\scf';
NOTE: Libname OUT refers to the same physical library as MYLIB.
NOTE: Libref OUT was successfully assigned as follows:
      Engine:        V9
      Physical Name: D:\SCF
FILENAME scf2007 'D:\SCF\scf2007';
PROC CIMPORT DATA=OUT.dataset INFILE=scf2007;
RUN;
ERROR: Invalid file, D:\SCF\scf2007.
NOTE: The SAS System stopped processing this step because of errors.
NOTE: PROCEDURE CIMPORT used (Total process time):

请问高人们是哪里出了问题，万分感谢！！！！！
