-----------------------------------

absolutely anything. You should be refactoring your code into usable functions anyway.

-----------------------------------

not just Turing
Code refactoring is any change to a computer program's code that improves its readability or simplifies its structure without changing its results.

function say_hello()
   put "hello"
end say_hello

put "the program will now greed you"
say_hello()
put "the program is now finished"


Perhaps you were in a hurry but it should be procedure not function


procedure say_hello ()
    put "hello"
end say_hello

put "the program will now greed you"
say_hello ()
put "the program is now finished"



To answer your orignal question. Functions and procedures are used to put repetative code only once.

Consider the following


function GetInput (what : string) : string
    put what
    var input : string
    get input
    result input
end GetInput

var firstName := GetInput ("Please enter your first name")
var lastName := GetInput ("Please enter your last name")


Vs.


var firstName, lastName : string
put "Please enter your first name"
get firstName
put "Please enter your last name"
get lastName
