The "cust_cur" looks like this, from my DECLARATION section...

• CUSTOMER table dursor CURSOR cust_cur IS SELECT ky_cust_no, nm_cust_1, cd_cust_type, cd_co, nm_cust_2 FROM customer WHERE cd_cust_type NOT IN ('1' , -- VS-NATIONAL 'F' , -- VS-GOVT-FEDERAL 'I' , -- VS-INDIVIDUAL 'M' , -- VS-GOVT-MUNICIPAL 'S' , -- VS-GOVT-ST 'T' , -- VS-GOVT-AUTH 'Y' , -- VS-GOVT-COUNTY 'E' ) -- VS-COMPANY-USE ORDER BY ky_cust_no; cust_rec cust_cur%ROWTYPE;
