data

Pop one item and push it back twice.

Note that it is a very good idea to use this action instead of duplicating data in a Push Data.

Pop one string representing the name of the property to be deleted. Then pop the object from which the property is to be deleted.

In version 5 through 8, it is necessary to Push Data type undefined (0x03)1 before the string as in:

96 04 00 03 00 'a' 00 3A
delete("a");

to delete a global variable.

• 1. Since player version 9, deleting a dynamic (global) variable requires _root (or _global) instead of undefined.

Declare a function which can later be called with the Call Function action or Call Method action (when defined as a function member.) The f_function_length1 defines the number of bytes that the function declaration uses after the header (i.e. the size of the actions defined in the function.) All the actions included in this block are part of the function body.

• 1. A function is limited to 65535 bytes.

Declare a function which later can be called with the Call Function action. The f_function_length1 defines the number of bytes that the function declaration takes. All the actions included in this block are part of the function. A function should terminate with a Return action. The value used by the return statement should be the only value left on the caller stack.

• 1. Functions are limited to 65535 bytes in length.

Declare an array of strings that will later be retrieved using the Push Data action with a dictionary lookup. There can be a maximum of 65534 strings. The visibility of a dictionary is within its DoAction or other similar block of actions. Note that you should have only one Declare Dictionary. The dictionary is visible from everywhere in the DoAction.

Pop a Boolean value; if true then jump to the specified action; otherwise continue with the following actions.

There is no Branch If False action. Instead, first use the Logical Not, then Branch If True.

IMPORTANT NOTES

Jump to the specified action. The offset is added to the current execution pointer as it is after reading the branch instruction.

IMPORTANT NOTES

The offset must be such that when added to the current execution pointer it points to a valid action (i.e. you cannot jump in the middle of a Push Data or any other multi-byte action.)

struct swf_definebinarydata {
	swf_tag			f_tag;		/* 87 */
	unsigned short		f_data_id;
	unsigned long		f_reserved;	/* must be zero */
	unsigned char		f_data[<variable size>];
};

The DefineBinaryData tag is used to save any arbitrary user defined binary data in an SWF movie. The Flash player itself ignores that data. The size of the data is not specifically limited.

The f_data_id is this object identifier. The identifier is the same type as any identifier (like a sprite identifier.) It is used in ActionScripts to reference the data.

The f_reversed area is 32 bits and it must be set to zero in version 9.

struct swf_definesceneandframedata {
	swf_tag				f_tag;		/* 86 */
	unsigned char			f_data[tag size];
};

This tag is used to define some raw data for a scene and frame. It is often used to include XML files in Flash animations.

f_data is an array of bytes.

struct swf_doabc {
	swf_tag			f_tag;		/* 72 or 82 */
	if(f_tag == DoABC) {
		unsigned long	f_action_flags;
		string		f_action_name;
	}
	swf_action3		f_action_record[variable];
};

^*the version specified here is the version in which the tags appeared—however, actions of higher versions can be used with older version tags and thus this version doesn't indicate the version of all the actions used in this tag

The DoABC and DoABCDefine are available since version 9. These are similar to the old DoAction and DoInitAction, yet the actions use a way different declaration scheme and they include flags and a name. This new scheme helps greatly in simplifying the definitions of ECMAScript classes and accelerate the access to the code tremendously.
