thanks..Sorry, you can't. There's no user input in PL/SQL.
You can use the SQL*Plus ACCEPT command to prompt the user for a value that gets stored in a substitution variable. You can then use that substitution variable in PL/SQL, but it will be resolved before the PL/SQL is compiled, not at run-time.
For example:
ACCEPT     happy_y_n     PROMPT "Are you happy today? (Y/N): "
SET     SERVEROUTPUT     ON
CREATE OR REPLACE PROCEDURE     happy_message
IS
BEGIN
     IF  UPPER ('&happy_y_n') LIKE 'Y%'
     THEN
          dbms_output.put_line ('That''s great!');
     ELSE
          dbms_output.put_line ('Hope you feel better soon.');
     END IF;
END     happy_message
/will create a procedure, but the user input is performed when you run the script above. When you execute the procedure, it uses whatever value the substitution variable &happy_y_n had when you compiled the procedure: it doesn't ask anything at run-time.
Other front-end tools (such as Forms) have their own ways of getting user input (such as dialogue windows).
