Exp bar

How do you change the exp bar to be like 0/100000 instead of 0/200. I need a really large number instead of just 200

Under gameplay constants there are four values:

Hero xp required - level factor, constant factor, previous value factor, and table. Allow custom values, and have at these.

I would go more into them, but it's late and I need to sleep. But any value in the table overides a value achieved from the other factors

Those in the Gameplay constants as Sadism said is the one you are looking for, but they are very advanced (i think). Me myself had a lot of problems with em, but after many tries I "almost" knew how they worked =)

Hint:
1.Create a new map with hero and low-lvl creeps.
2.Change 1 of the four values, and test map
3. Repeat the 2nd step until u see what they change.. and how they change it.
