How to convert String to Date value in SAS? -

I want to change the string to date in the SAS, I tried:

  Data_null_; Monay = '05 May 2013 '; Date = input (substrate (bandage, 1,9), yammed.) ;; Put date = date 9.; Run;   
 But it was not working, can it be done?   
 
 
 You do not need substr or tabs.  
  input (monyy, date9.);
