CS Fundamentals: How to Create a Simple Function

You've already learned to use and edit
functions as a part of an efficient

program. Now, let's learn how to create
and use a function from scratch. To do

this, look for the category called
functions in the toolbox. Here, you'll see

a block called "do something". Drag that
block out into your workspace and rename

it to something new that better
describes what your function will do. I'm

calling this one "make a square". From here,
you can drag blocks into the function to

specify what you want to happen when the
function is used. With our function

created, you can see that a new make a
square block appears under the functions

label in the toolbox, so that we can
actually use, or "call", our created function

from our program. This is an important
step that's easy to forget. Okay, time to

continue on and get creative with your
own functions!
