about my source code?

Can you make this source code into 5 procedures and 1 function into an arrangement order?
this source code is to arrange an input into an ascending order or descending order.

uses crt;
var n1,n2,n3,n4,n5 : real;
    ans:string;
    opt:char;

procedure ascending(var a1,a2,a3,a4,a5 :real); forward;

          end;

            descending(n1,n2,n3,n4,n5);
