Part 1

Create a (JASS) trigger that runs (only) when Hero makes a point order.
Create a (JASS) trigger that runs (only) when Hero makes a target order.
Create a (JASS) trigger that runs (only) when Hero makes an order without target.

Create a (JASS) trigger that runs when you select the Hero.
The trigger's goal is to print following values on screen:

1. PointOrders: X
   
2. TargetOrders: Y
   
3. NontargetOrders: Z

... where, X, Y, Z are the correct values respectivly how much orders the Hero did (like counters).

Tip: You must use the first three triggers to count the different orders, and use hashtable to bind the values to the unit.

Part 2

Create a (JASS) trigger that runs when a player presses the 'Esc' button.
The trigger's goal is to clean the hashtable of all it's entries.

[IcemanBo]

Data is saved to an non-hero-related constant value. -- simply "0" is used as parent key to data access.
This means the data is not really binded to the hero unit who made the orders, and putting in some more units would make it not possible to distinguish data for each unit.
