End a record of actions. There are no valid instances where this action is optional.
The End action itself as no meaning other than marking the end of the list of actions. Yet, if reached, the execution of the script ends and is considered complete.
IMPORTANT NOTE
This action ends a complete list of actions. Declare Function, With, try/catch/finally and other blocks of actions are never ended with this action. Instead, internal blocks have a size in bytes1 that is used to determine the end of the block.
This is different from the End tag that is used inside a Sprite to end its list of tags.
