Another was is a system variable called $PWR_NORMAL, during normal power cycle startup it runs a .CF (command file), where you run your programs.
I think you would just type the folder and name of the .CF file without the extension. example: $PWR_NORMAL = FR:/START
To create a .cf file
example of START.CF created in notepad where it loads a tp program and a pc program, then loads the vr files of the pc program and runs it.
