Hi there

im writing a class which produces refrences in a hash
however im trying to deal with multiple authors
so i want to write an if statement where

if the key already exists
  push value onto it

im unsure of how to do this so any help would be much appreciated

many thanks

code:
class Reference

  @data

  add_field(field, value)
    if key already exits
      push value onto it
    else
     @data[field]=value
  end

  get(field)
    @data[field]
  end
end
