Definitions

So DrRackert let's me make definitions in the top window, but then it calls these constants, like if I do a simple

(define a 10)

If I try to re-define or set! a 15 then the interpret gets angry and says that a is a constant

How do I define something that can change values?

TL-DR. Use

(define my-height "MY ANUS")
(set! my-height 200)
so it will not be considered as constant by repl.
