What is this up arrow to the number 10 in the example with the constant method below?

Question

To make it clear and concise:

1. What is it? 2. Why is it there? 3. How to type it with a normal Keyboard? 4. Thanks! 

Answer 1

Character ^ . :) The return statement in smalltalk.

I don’t know if the default display function is included in latex, but the up arrow is used ^ .

On a regular keyboard, you can enter this character by pressing Shift + 6

Answer 2

For recording purposes only, in older versions of Pharo, the ^ symbol was printed as an up arrow. So, as Yuri says, enter ^ to return the up arrow.

This behavior no longer exists in recent versions of Pharo: ^ prints as ^ .
