in thread Read CSV with column mapping

Thanks. This worked for me now. On the side note. How can I implement object oriented concept (encapsulation) in this same scenario? e.g. if I want to do following.
-> sub Initialize read config file and construct hash and return self object sub get_value(string parameter, string key) return value
config file:
parameter, key, value, id abc, xyz, 1, 100 blue, pqr, 0.1, 101
