After a tidy up (and using the Code window which is the {i} above post area):

data ex1;
  date='09sep2018'd;
  output;
  date='10sep2018'd;
  output;
  date='11sep2018'd;
  output;
  date='12sep2018'd;
  output;
  format date date9.;
run;
proc format;
  value jj 
    low-'10sep2018'd=[ddmmyyd10.]
    '11sep2018'd-high=[date9.];
run;
data ex2;
  set ex1;
  new=date;
  format new jj.;
run;
