I'm fairly certain that while you could run code with eval() it wouldn't
have any side effects. It was some sort of temporary scope that was thrown
out after execution or something, or you could only get side effects by
calling a function. But, last time I wrote AS2 code, it was on Flash MX so
my memory is hazy ;-)
While I'm also from a graphic design background, I'm a pretty experienced
Java etc programmer so I came to Flex from that perspective. I might not
always be the best person to understand your point of view when you're
asking questions, but I'm willing to give it a shot :)
Also when you're asking a question like the original, we're better able to
help if you provide some context as to what you're trying to achieve, as
well as the technical quesion you're asking.
What I mean is, the technical question is "how do I emulate eval('movie_' +
number)", but the context is "I'm trying to create a scrollable list of 6
text boxes". That way we know whether answering your question is enough, or
if we should give you a nudge to a more "flex-like" solution, such as
"here's how you do that, but you probably want a List component"
