== Why is this an issue?

By default, the parameter mode is ``++IN++``. However, specifying it explicitly makes the code easier to read.


=== Noncompliant code example

[source,sql]
----
SET SERVEROUTPUT ON

DECLARE
  PROCEDURE printName(name VARCHAR2) AS -- Noncompliant; relies on default mode
  BEGIN
    DBMS_OUTPUT.PUT_LINE('name: ' || name);
  END;

BEGIN
  printName('Foo');
END;
/
----


=== Compliant solution

[source,sql]
----
SET SERVEROUTPUT ON

DECLARE
  PROCEDURE printName(name IN VARCHAR2) AS
  BEGIN
    DBMS_OUTPUT.PUT_LINE('name: ' || name);
  END;
BEGIN
  printName('Foo');
END;
/
