How to use of variable sized parameter in plsql procedures

Question

Hello,
We will write a procedure which has a fixed parameter and which has other variable count parameters. How can we implement with this in pl - sql., which structure(varray, nested table, collections vb) should we use?
For example:
I want to use it like below:
create procedure TestProc
paramId Number,
paramOthers
IS
-- variable declarations
vOthers
begin
select paramOthers
into vOthers from table1;
-- some other sqls
dbms_output.putline( vOthers[0] || ' some message ' || vOthers[1] || ' some other message' || vOthers[3] || ' anoother message... ' || vOthers[n] );
end TestProc;
/

I also tried but I am taking errors:
My simple code is:
( I have not to try to use values in array as column names in select statement yet )
/* Formatted on 2008/09/26 10:35 (Formatter Plus v4.8.8) */
CREATE OR REPLACE PACKAGE TEST_PACKAGE
AS
TYPE VARCHAR2_ARR IS TABLE OF VARCHAR2 (50);
FUNCTION TEST_FUNC (S IN NUMBER, MY_PARAM_ARR IN VARCHAR2_ARR)
RETURN VARCHAR2;
END TEST_PACKAGE;
CREATE OR REPLACE PACKAGE BODY TEST_PACKAGE
IS
FUNCTION TEST_FUNC (S IN NUMBER, MY_PARAM_ARR IN VARCHAR2_ARR)
RETURN VARCHAR2
IS
V_COUNT NUMBER;
VSTRING VARCHAR2 (10000);
BEGIN
VSTRING := '';
V_COUNT := MY_PARAM_ARR.COUNT;
FOR TEMP_VAR IN 1 .. V_COUNT
LOOP
VSTRING := VSTRING || MY_PARAM_ARR (TEMP_VAR);
END LOOP;
RETURN VSTRING;
END TEST_FUNC;
END TEST_PACKAGE;
DECLARE
MY_ARR TEST_PACKAGE.VARCHAR2_ARR;
RETVAL VARCHAR2 (20000);
BEGIN
MY_ARR (1) := 'Test1';
MY_ARR (2) := 'Test2';
MY_ARR (3) := 'Test3';
MY_ARR (4) := 'Test4';
SELECT TEST_PACKAGE.TEST_FUNC (3, MY_ARR)
INTO RETVAL
FROM DUAL;
DBMS_OUTPUT.PUT_LINE (RETVAL);
END;
I take the error message below:
ORA-06550: line 10, column 38:
PLS-00642: local collection types not allowed in SQL statements
ORA-06550: line 10, column 24:
