A call to GET_ITEM_PROPERTY(item_name, ITEM_TYPE) can be used to verify the item type
before calling CHECKBOX_CHECKED.
To set the value of a check box programmatically, assign a valid value to the check box using standard
bind variable syntax.
Parameters
item_id Specifies the unique ID that Form Builder assigns to the item when it
creates it. The data type of the ID is ITEM.
item_name Specifies the string you defined as the name of the item at design time. The
data type of the name is VARCHAR2.
CHECKBOX_CHECKED restrictions
The CHECKBOX_CHECKED built-in returns a BOOLEAN value regarding the state of the given check
box. It does not return the actual value of the check box nor does it return the value you might have
indicated for the Mapping of Other Values property.
