GET_LINE or GET_LINES, how?

Question

Hi,
I need to make stored procedure which will be called from SQLPlus and this procedure have to use input values to insert it into some table.
But i have problem. Next code simple doesn't work:
SQL> set serveroutput on
SQL> declare
  2  v_line varchar2(200);
  3  v_status number;
  4  begin
  5  dbms_output.get_line(v_line, v_status);
  6  dbms_output.put_line(v_line);
  7  end;
  8  /
PL/SQL procedure successfully completed.
Why?
I hope that this problem is already solved.
My idea is final procedure something like this:
create or replace procedure insert_txt is
  v_line   varchar2(200);
  v_line2 varchar2(200);
  v_status number;
begin
  dbms_output.put_line('Enter some text:');
  dbms_output.get_line(v_line, v_status);
  dbms_output.put_line('Enter another text:');
  dbms_output.get_line(v_line, v_status);
  dbms_output.get_line(v_line2, v_status);
  insert into txt_table values (v_line,v_line2);
end;
so i can call it from sqlplus:
set serveroutput on
begin
  insert_txt;
end;

Review what dbms_output.get_line does:
http://docs.oracle.com/database/121/ARPLS/d_output.htm#ARPLS67319
It retrieves a string previously stored by put_line.  If you haven't called put_line yet, then there won't be anything stored for you to retrieve.
What is the big picture here?  What business problem are you trying to solve?  If you can explain what you want to do in English, then someone can help you find a good way to do it in PL/SQL.
