please learn the basics. It also lets you ask better questions which will lead to better answers for you ;-)

By writing the code to perform the required actions depending on which key is pressed. If you have an actual programming problem then please provide the details.

[edit]
I am reminded of my answer to your previous question at How do I create a if up key pressed, go up code?[^].

As mentioned in your later question today, actually learning the language would be a better use of your time than posting all these questions here.

When I played 'Snake][' on Apple ][, I used to use 2 keys only.
1Key is 'turn left', the other is 'turn right'
The advantage, only 2 finger needed and no need to check if doing a 'U turn'

I was assume that WASD refers to the keyboard's keys used for directions in games. You obtain input from the user and translate W to a value that means up to you, A will mean left, D will mean right, etc. That means you have to define values for the four directions that mean something to your code and return one of those depending on which key the user presses. You have not specified an OS and that will make a difference to your implementation.
