DECLARE
TYPE   CharArrayTyp   IS   TABLE   OF   VARCHAR2(50)     INDEX   BY   BINARY_INTEGER;   
TYPE   NumArrayTyp     IS   TABLE   OF   INTEGER               INDEX   BY   BINARY_INTEGER; 
   
CREATE OR REPLACE  PROCEDURE   GetVoiceMsg(             sql_no_value         in           VARCHAR2,   
          Sql_no_length       in           INTEGER,   
          v_type                     out         NumArrayTyp,                                     
          v_musicid               out         CharArrayTyp,                               
          v_name                     out         CharArrayTyp                               
      )AS v_1 NumArrayTpe ;
      
      
      begin 
      v_1 :='abcdef';
      v_type:=v_1;
      dbms_output.put_line('N1:'||TO_CHAR(v_type(1)));
      end;
