Trying to reference field name of my record Type in my procedure!

Question

Hello,
I am stuck. I am trying to reference field names in my record type declared in my Package declaration.
Here is an example. Don't be scared, it's a very simple package. I just need some directions what to use to accomplish this.
--look into this part of the package body
FOR cur_rate IN c_rate
LOOP
rate_data(1).field_name := cur_rate.rate_pct;
--field name = AK_PCT, AL_PCT and so on ...
END LOOP;
END rate_tab_qry;
CREATE OR REPLACE PACKAGE rate_pkg IS
TYPE rate_rec IS RECORD (
id cycle_rates.id%TYPE
,cycle cycle_rates.cycle%TYPE
,scac cycle_rates.scac%TYPE
,gbloc cycle_rates.gbloc%TYPE
,code cycle_rates.code%TYPE
,AK_PCT cycle_rates.rate_pct%TYPE
,AL_PCT cycle_rates.rate_pct%TYPE
,AR_PCT cycle_rates.rate_pct%TYPE
,so on...
TYPE cycle_rate_tab IS TABLE OF rate_rec INDEX BY BINARY_INTEGER;
PROCEDURE rate_tab_qry(rate_data IN OUT cycle_rate_tab,
p_id cycle_rates.id%TYPE,
p_cycle cycle_rates.cycle%TYPE,
p_scac cycle_rates.scac%TYPE,
p_gbloc cycle_rates.gbloc%TYPE,
p_code cycle_rates.code%TYPE);
END;
CREATE OR REPLACE PACKAGE BODY rate_pkg IS
PROCEDURE rate_tab_qry(rate_data IN OUT cycle_rate_tab,
p_id cycle_rates.id%TYPE,
p_cycle cycle_rates.cycle%TYPE,
p_scac cycle_rates.scac%TYPE,
p_gbloc cycle_rates.gbloc%TYPE,
p_code cycle_rates.code%TYPE)
IS
CURSOR c_rate IS
SELECT state, rate_pct
FROM cycle_rates
WHERE cycle = p_cycle
AND scac = p_scac
AND gbloc = p_gbloc
AND code = p_code;
BEGIN
rate_data(1).id := p_id;
rate_data(1).cycle := p_cycle;
rate_data(1).scac := p_scac;
rate_data(1).gbloc := p_gbloc;
rate_data(1).code := p_code;
FOR cur_rate IN c_rate
LOOP
rate_data(1).field_name := cur_rate.rate_pct;
--field name = AK_PCT, AL_PCT and so on ...
END LOOP;
END rate_tab_qry;
I need to know, how to reference my field name for each state in my procedure that are in my record type. The problem is it won't allow me to use something like this.
select state || '_PCT
from cycle_rates;
which would eventually show me each state concatenated with '_PCT, e.g. AK_PCT and that's my field names.
For example,
FOR cur_rate IN c_rate
LOOP
rate_data(1).field_name := cur_rate.rate_pct;
--field_name = AK_PCT, AL_PCT and so on...
END LOOP;
I would appreciate it if somene can direct me. Thanks.

This is a sample output from my cusror. Just to make it easier for you guys to see it.
ST RATE_PCT
AK 0
AL 2
AR 2
AZ 2
CA 2
CO 2
CT 2
DC 2
DE 2
FL 2
Hope it helps.
