? on How to Load Variable Within For Loop

Question

Hello,
I'm a PL/SQL newbee so I apologize up front if this is a basic question. In summary, I'm trying to build a field name within a FOR LOOP and also load this field with it's associated data from an input record and finally load the data to the output record and pipe the row. I can successfully build the field name but don't know how to load it with data from the input record.
Here is a sample from the code.
The input table is shown with the 6 different Fnma codes. Instead of checking each code for data, I want to build the field name, load this field name with data from the input record and move the data to the output record.
CURSOR cur_loan(prod_date_in IN DATE) IS
Select
Ln.Ln_No,
Ln.Prod_Date,
Ln.Ln_Fnma_Ftr1_Cd,
Ln.Ln_Fnma_Ftr2_Cd,
Ln.Ln_Fnma_Ftr3_Cd,
Ln.Ln_Fnma_Ftr4_Cd,
Ln.Ln_Fnma_Ftr5_Cd,
Ln.Ln_Fnma_Ftr6_Cd,
from LOAN Ln
where PROD_DATE = '16-FEB-11';
Here is the FOR LOOP that successfully builds the field name in l_feat_code_name. Then I "assume" by moving this field to l_output that l_output will contain the actual data, not the field name. However, it appears to contain the field name instead of the data.
FOR l_To IN 1 .. 6
LOOP
l_feat_code_name := ('l_loan_rec.ln_fnma_ftr'||l_to||'_cd');
l_output := l_feat_code_name;
IF (l_output is not null or
l_output <> ' ') THEN
l_out_rec.Inv_Type := l_Fnma_Cd;
l_out_rec.feat_code := l_output;
l_out_rec.Src_Delete_Flag := l_src_delete_flag_n;
PIPE ROW(l_svc_ln_rec);
END IF;
END LOOP;
How can I move the data itself into the l_out_rec.feat_code output record? Thanks in advance.

Hi,
l_output is defined as follows:
l_output varchar2(20) ;
I appreciate your example.
Again, after I build l_feat_code_name it contains the column name from the input record, Ln_Fnma_Ftr1_Cd, ....Ftr2...., .....Ftr3..... and so on up to Ftr6. However, I also need the **data value** of Ln_Fnma_Ftr1_Cd, ....Ftr2...., .....Ftr3..... and so on up to Ftr6. My question is how to get the data value. You see below when I move l_feat_code_name to l_output I'm expecting l_output to contain the **data value**. Instead, when I display it in DBMS_output, it shows the column name.
