SubString (multi-byte)

Pop one string, compute the ASCII value of its first character and put it back on the stack.

This function does not take UTF-8 in account. In other words, it can be used to parse a string byte per byte. To get the UTF-8 value of characters, use the Ord (multi-byte) instead.

Cast Object

String

Pop one item and transform it into a number (integer or floating point.) If a1 is already a number, it is simply pushed back on the stack.

For strings it works as you would expect (see the strtof(3C) manual pages).

For a user defined object, the method named valueOf() is called. You can declare that function on your own objects to get this action to retrieve the value.

Declare Object

Pop the name of a method (can be the empty string), pop an object1 (created with the Declare Object,) pop the number of arguments, pop each argument, create a new object, then call the specified method (function s1 if defined, otherwise function s2) as the constructor function of the object, push the returned value on the stack. This allows for overloaded constructors as in C++.

  • 1. Yes. This contradicts the definition above. I will have to confirm which is correct.

Set Member

Pop the class name for the new object to create. Pop the number of arguments. Pop each argument (if i2 is zero, then no arguments are popped.) Create an object of class s1. Call the constructor function (which has the same name as the object class: s1). The result of the constructor is discarded. Push the created object on the stack. The object should then be saved in a variable or object member.

Set Variable

Pop one string, search for a variable of that name, and push its value on the stack. This action first checks for local variables in the current function. If there isn't such a variable, or the execution is not in a function, then the corresponding global variable is read.

The variable name can include sprite names separated by slashes and finished by a colon as in. Only global variables are accessible in this way.

Get URL
FSCommand2

Pop two strings, the URL (s2) and the target name (s1).

All the usual HTML target names seem to be supported (_top, _blank, <frame name>, etc.) You can also use the special internal names _level0 to _level10. _level0 is the current movie. Other levels, I'm still not too sure how these can be used.

Get URL2

Load the specified URL in the specified target window.

When the target is set as "_level0", the current SWF file is replaced by the file specified in the f_url field. The name in the f_url field should be a proper SWF file or the area will simply become black.

When the target is set as "_level1", something special is supposed to happen. I still don't know what it is...
Also the effect of _level1 + an empty URL is ... (to remove level1?)

Call Method
Get Member
Set Property

Query the property n1 of the object named s2 (a field in a structure if you wish), and push the result on the stack. Note that since version 5, it is preferable to use Get Member or Call Method when a corresponding variable or function member is available on the object.

The following is the list of currently accepted properties or fields for the Get Property and the Set Property actions. Note that the properties can be specified with either an integer (type 7, requires V5.0+) or a single precision floating point (type 1, V4.0 compatible). And since strings are automatically transformed in a value when required, one can use a string to represent the property number (type 0). It works with a double value, I even tested a Boolean and null and it works. Obviously it isn't a good idea to use these. The default should be a single precision float. Please, see the Push Data action for more information about data types.

WARNING: Adobe is trying to phase out this functionality. It is very likely not working in ABC code and it is not necessary since objects have member functions that can be used for the exact same purpose and it is a lot cleaner to use those instead.
