'creating new variables in sas

I am trying to create 3 new variables and have used this code however keep getting an error in my log, I am not sure what this issue is:

    Data birthdata
    SET birthdata;

    native=.;
    if race=3 THEN native=1;
    if race=1 THEN native=0;

    aarace=.;
    if race=2 then aarace=1;
    if race=1 then aarace=0;

   nonwhite=.;
   if (1<race=.) then nonwhite=1;
   if race=1 then nonwhite=0;


  label native  = "Maternal race"
  aarace  = "Maternal race"
  nonwhite = "Maternal race";

 FORMAT native native. aarace aarace. nonwhite nonwhite.;

 run;
