1. Program! (tune = "Dreidel!")
I have a computer program.
I made it out of codes.
And when it is started,
Oh program, think of all the modes!
Oh code, code, code,
I made you out of a method.
And when you’re being written,
Code, you’re understood!
Oh method, method, method,
I made you out of commands.
And when you have an error,
I shall give you demands!
Oh command, command, command,
I mage you out of variables.
And when you are inputted,
I will make up symbols!
Oh program, program, program,
You are in the terminal.
And when you are tested,
I shall make it final!
