I need to parse data similar to the following into separate columns -
one column for last name, one column for first name and middle initial
(or middle name) and one column for zip code. What is the best way to
do this (least number of steps).

Smith, John J 80909
Carson, Mary S 80222
Cleaver, Wally 80002
Jones, John Paul 80019
Latham, Stella G 90002

Thank you.
