(Help) making combat arms program

Hey i'm making a program useing notepad How can i make it to open combat arms and run it as soon as the program starts should i put echo run engine.exe ( Or what any help on making programs on injectors would be very helpfull and I'm very new to making programs and any pointers would rock ) Rep to anyone that really helps
(sorry for spelling errors)

Isn't it:

system.start Engine.exe?
