I'd go with this too... if you want an ELSE, then might as well use it.... ;-)


I haven't tested this in Macromedia Flash myself, but it seems similar to

what we see in Lingo and other languages: a handler fully executes, and a

navigational change does not prevent this.


In BASIC you would actually jump immediately to new code on that "GoTo"

command, because "goTo" there moves around various blocks of code. In a

procedural language "goTo" moves the execution point in the big mass of

executable lines.


In an event-driven language like Lingo or ActionScript, a "goTo" moves the

playback head. It doesn't stop the rest of the script from executing. Even

though the playback head moves to frame 3 in one command, it immediately

moves to frame 5 in the next command.


I haven't tested fully against this in Macromedia Flash myself yet, but

what you describe seems consistent in other event-based environments. Does

this ring true for you, too...?


Summary: A "goTo" moves the playback head, but handlers still execute fully.
