How about something like this instead?

data=Hash.new
["street number","street name","city name","state","zip code"].each do |i|
puts("Please enter your #{i}: ")
data[i]=gets.chomp
end

HTH,

Well, there's always more than one way to do anything,
but here's one late night hack :)

#!/usr/bin/env ruby

class ResumeBuilder
def initialize
@data = {}
@fields = ['First Name',
'Last Name' ,
'Address' ,
'City' ,
'State' ,
'Zip' ]
end

def prompt
@fields.each do |field|
val = @data[field]
print "Please enter your #{field}#{(' (' + val + ')') if val}:"
val = gets.chomp
@data[field] = val if val != ''
end
end

def confirm?
puts "You entered:"
@fields.each do |field|
puts field + ': ' + @data[field].to_s
end
print "Is this correct? (Y/n)"
gets.chomp == 'Y'
end
end

resume = ResumeBuilder.new
resume.prompt
resume.prompt until resume.confirm?

I didn't bother with the formatting, but you get the idea.
You might also look at using a Struct.
