We tend to use them to specify private properties.
class MyClass
{
private var _something1:Number;
public var something2:Number;
}
Partly because it then makes replacing a public property with a
getter/setter pair easy:
class MyClass
{
private var _something1:Number;
private var _something2:Number;
public function get something2():Number {return _something2;}
public function set something2(num:Number):Void {_something2=num;}
}
and partly because it's easier to think up names in situations like:
class MyClass
{
private var _something1:Number;
public function MyClass(something1:Number)
{
_something1=something1;
}
}
It's a just a convention we use in-house; there aren't any
Actionscript Community wide hard-and-fast rules about it.
Of course, Macromedia themselves vary whether they use underscores or
not for public variables, and I've never figured out the rhyme and
reason. Why _x and _y and _visible but not _enabled? Why not just x
and y?
Cheers,

I've noticed many class authors prefix property names with an underscore, or
2 underscores or none at all. I often see all three of these prefix 'styles'
in one class. I haven't been able to figure out what the convention is.
Please show me the light.
Thanks
