If you use proc reg. You can use outest option to store estimates. See example below,

data t1;
   do i=1 to 100;
      x=rannor(123);
          y=1+2*x+rannor(123);
      output;
        end;
run;

proc reg data=t1 outest=param;
model y=x;
run;
quit;

proc print data=param;
run;

谢谢了，尽管不是我想要的，但依然感谢
