I have a flat text file that looks like this
Mr and Mrs Smith
19 Elm Street
Boston, Ma 01231

Mark Hanson
Kathy Elmstead
13 sycamore drive
Bolston Mt 91320

Mark and Linda Everett
342 Pine Street
Austin, Tx 53221

it goes on for about 500 entries

I'd love to get it into this format

Mr and Mrs Smith 19 Elm Street Boston Ma 01676
etc

any clever ideas

thanks
Lowell
