String Sorts

I have a stirng array of about 300 names. I need to sort them to put them in alphabetical order. I have been trying to use the bubble sort example, but comaring and replacing in a string array seems to choke.

My data is in the format: lastname, Spouse1 & Spouse2

Do the "," and "&" pose problems to a string array ?
Does the "immutable" factor apply to string arrays ?

I'm learning but still struggling !

Thanks.
Bob
