Mike,
When I do a read it doesn't find the engine
The READ command has nothing to do with adding and running engines.
and I don't know how to add an engine yet
If you don't first add the engine, you cannot start it up and run it.
I am slowly working threw your book
Read the section on Menus to add and operate DCS engines. In The DCCS Companion 3rd Edition, that would be:
