function mp3Player ('arg1', 'arg2')</pre> |

2. There may be "stacked" function declarations |

<h2><a name="wishlist">Wishlist</a></h2> |

<pre> |
| 122 |
- komplexere verschlüsselung als "-1, -2 ..." z-b nicht in der numerischen reihenfolge sondern nach |
| 123 |
zufallsprinip (-21,-3,-89)? (->random) |
| 124 |
- evtl. constants nach abfrage ersetzen ? leider sehr aufwendig, bei vielen constants (->ask) |
| 125 |
- rausgeben des arrays mit den "neuen" werten um evtl die obfuscation rückgängig zu machen (->undo) |
| 126 |
- " push 0 |
| 127 |
ls: |
| 128 |
dup |
| 129 |
trace |
| 130 |
branchIfTrue ls" |
| 131 |
... after each "constants" declaration (->pollute) |
| 132 |
- what about other symbols beside "function"s? (e.g. variables) (->mode)</pre> |
| 133 |

| 134 |
</p> |
| 135 |
<h2><a name="notes">Notes</a></h2> |
| 136 |
<pre> |
| 137 |
- no function may be called "Initialize", rename it to (e.g.) "Initialize2", reassembling will not work otherwise |
| 138 |
(doesn't matter when obfuscating since function names will be replaced of course) |
| 139 |
- function names seem to be/work case insensitive (shuffle <-> Shuffle) |
| 140 |
- successfully tested with <a href="http://download.macromedia.com/pub/flash/showme/win/puzzle.zip">http://download.macromedia.com/pub/flash/showme/win/puzzle.zip</a> |
| 141 |
- make sure -1, -2, -3, .... gets replaced with '-1', '-2', '-3', ... |
| 142 |
- there are multiple caller lines: callFunction, callMethod; do we have to take special care to methods? |
| 143 |
- "getMember" and "getVariable" also do function calls! |
| 144 |
- there are reserved function names which must not be replaced! (-> event handlers, e.g. "onPress")</pre> |
