在delphi中添加多个函数调用？

function Function1(Param1: Integer; Param2: String): Integer;
begin
  // 函数1的实现
end;

function Function2(Param1: String; Param2: Boolean): String;
begin
  // 函数2的实现
end;

function Function3(Param1: Double; Param2: Integer): Double;
begin
  // 函数3的实现
end;

uses
  MultiFunctionCall;

var
  Result1, Result2: Integer;
  Result3: Double;
begin
  Result1 := Function1(10, 'Hello');
  Result2 := Function2('World', True);
  Result3 := Function3(3.14, 42);
end;
