I currently have a large text file based  address book(for myself, not 
spamming)  that  I am working on making suitable for import into a 
database.  To do this I need comma separated values.  How would I go 
about adding a comma after the state in the person's mailing address?
An example record:

Name:  Bob Fakeyhead
Title:  Old Boss
Phone:  555-555-5555
Mailing:  23456 Something Street
OldPlace, WA 55555

I need a ',' after WA.
Right now I am reading the file into a string to edit it and then 
writing the comma separated version back out to file.  For most of the 
other fields I can just add a comma to the end of each line and get the 
desired effect but for the Address I need to have multiple fields and 
therefore multiple commas per line.

Thank you,
Matthew Margolis
