               4.4 YEARCUTOFF:

               Year cutoff is used to resolve conflict raised for selecting country due to two digits used in year

               Default year cutoff is 1920 and it considers 100 year means from 1920 to 2019.

               You might consider  including a statement such as the following  in each of  your programs in case the
               version of SAS you are using changed the default value of this option:
               Optionsyearcutoff=1920;

               4.5 Difference between function and call routine?

               SAS function always returns a single value and the arguments do not change their value when function is
               executed.  But  call  routine  can  be  used  to  retrieve  more  than  one  value  and  argument  used  in  a  call

               routine can change their value.

               Functions can be used in an assignment statement but call routine cannot.
