How to create a program? Help!?

Hey guys. So basically i want to make a program in ComupterCraft. Lets call this program "Film"
So i do - edit film - and it will take me to a blank page where i can make it do something. So i could do
print("Hello") and i save and exit then if i do film it will print Hello
But what i want to do is when i type Film i want it to run another command and i want that command to be
monitor back secret/alongtimeago
as this is for my servers cinema so it would run the movie on the big monitor on the back.
Yes i have tryed to do
print("monitor back secret/alongtimeago") and
write("monitor back secret/alongtimeago")
but i do it and it doesnt run the program it just shows me on the screen. HELP!?
Thanks all

If you want the program to run you should use the shell.run command.
For example: shell.run("monitor", "back", "secret/alongtimeago")
