what does this Actionscript code mean?

[ampped80]

Could someone tell me what this code means? (Actionscript 2.0)

On the maintime I have this code on frame 1
_root.g_page = 0;
_root.page = 0;

then this code is attached to a button
on (release)
{
_root["b" + _root.g_page].gotoAndPlay("s2");
_root.g_page = 1;
_root.page = 1;
_root.play();
_root["b" + _root.g_page].gotoAndStop("s3");

I am trying to figure out especially what this g_page means. From looking through this template I purchased it appears to be a variable declared from the main time line. However, I get confused when I see...

_root.g_page = 0;
_root.page = 0;

Could someone explain the code above and tell me how "_root.g_page = 0;" and "_root.page = 0;" are related to one another (or if they are related).

I would appreciate your help!

It just looks like they are two variables to me, but with a similar name, likely they have a similar task. Without seeing the whole project it's hard to say ther exact role.
