Nixer6, scripting should not be considered in isolation.
You end up writing convoluted scripts to do something that can be achieved with a simple trigger or waypoint, or better unit placement, or more playtesting, or ....
If you wish to consider the OFP scripting language as something worthy of intellectual study in its own right, then all you really need is the comref - it's all in there.
My Beginner's tute lists several scripting tutorials.
I also recommend that you read the comref from start to finish, like a book. Don't get bogged down trying to understand every command, just get a feel for what's in there.
