This may be a silly question: I want to store data that looks like: 
$hash{key} = "|1,2,3|mail1 address|mail2 address"

[download]
What happens if I want to add another address to an existing record such that: 
$hash{key} = "|1,2,3|mail1 address|mail2 address|page1 
address"

[download]
Do I have to read/rewrite the entire file?
