Subject: Problem With eval and each_index

I am trying to set a group of variables to values stored in a tab 
delimited string.  I have no problem splitting the string into an array, 
call it e, or in putting the variable names in a second array, call it 
v.  The problem arises when I try to merge the two together.  If I enter:
irb(main):073:0> p v
["name", "street", "city", "state", "zip", "*", "telephone"]
=> nil
irb(main):074:0> p e
["John Doe", "123 Main St", "Anywhere", "US", "01234-5678", "ab123", 
"1234567890"]
=> nil
irb(main):075:0> eval "#{v[0]} = e[0]"
=> "John Doe"
irb(main):076:0> p name
"John Doe"
=> nil

it works as I want.  But when I try:
irb(main):077:0> v.each_index {|i| eval "#{v[i]} = e[0]"}
=> ["name", "street", "city", "state", "zip", "*", "telephone"]

and then enter: puts zip
it returns with a NameError saying that the variable was undefined.

Am I missing something, or should I be trying a different method to 
accomplish this?
