Run a function · in code: Calling a Function

What it does

Runs one of your functions. The program steps into the function, runs its blocks, then comes back here and carries on.

Use it for

Using your function: total = addTax(100, 5).
Running the same steps at different places, with different values.

What to fill in

Run it on: Only for a method: the object to run it on, like pet. Leave it empty for a plain function.
Which function: The function's (or method's) name, like addTax or feed.
Values to give it: In the same order as its names, separated by commas, like 100, 5. Any maths works, like price * 2.
Store the answer in: The name of a value to keep what the function gives back, like total. Leave it empty if it gives nothing back.
