PROCEDURE event (event_name VARCHAR2)
IS
--
-- This procedure allows you to execute your code at specific events
-- including:
--
-- ZOOM
-- WHEN-NEW-FORM-INSTANCE
-- WHEN-NEW-BLOCK-INSTANCE
-- WHEN-NEW-RECORD-INSTANCE
-- WHEN-NEW-ITEM-INSTANCE
-- WHEN-VALIDATE-RECORD
--
-- Additionally, product-specific events will be passed via this
-- interface (see the Applications Technical Reference manuals for
-- a list of events that are available).
--
-- By default this routine must perform ‘null;‘.
--
-- Oracle Corporation reserves the right to change the events
-- available through this interface at any time.

/* Sample code:
form_name varchar2(30) := name_in(‘system.current_form‘);
block_name varchar2(30) := name_in(‘system.cursor_block‘);
param_to_pass1 varchar2(255);
param_to_pass2 varchar2(255);

-- Zoom event opens a new session of a form and
-- passes parameter values to the new session. The parameters
-- already exist in the form being opened.

SESSION_FLAG=>‘Y‘,
OTHER_PARAMS=>‘ORDER_ID="‘||param_to_pass1||

-- all the extra single and double quotes account for
-- any spaces that might be in the passed values

-- This is an example of a product-specific event. Note that as
-- of Prod 15, this event doesn‘t exist.
