Scheme Procedures

• A Scheme procedure is defined using DEFINE

  • e.g., a function which takes an argument and adds 1 to it
    (define increment
    
    (lambda (n) (+ n 1)))
    
    • Note lack of type declarations among arguments to functions
      
      

• LAMBDA can be thought of as an abstraction operator

  • e.g., we turn (+ 10 1) into the increment operation by replacing number to be incremented by a bound variable
    (lambda (n) (+ n 1))
