关于一个函数的参量指派，一直没搞明白，只怪自己太笨，还望各位大哥帮帮小弟！

上面的代码里有个函数是CRC16校验函数，在论坛里找到的！
小弟现在想实现在一个FORM上的EDIT输入一个数组，然后按钮触发对其进行CRC校验，然后在memo中显示，但是现在BuffCalCulateCRC(pCharx2;1);总出问题，说参量不够！
说白了我就是不明白调用Function   BuffCalCulateCRC(InputBuff:Pchar;BuffLen:integer):TMyCRC;时怎么指派参量，
各位大哥帮帮我这个菜鸟，着急啊，想了两天了！
先谢谢各位了！

Answer 1

BuffCalCulateCRC(pCharx2;1);
                        |--------不对

Answer 2

BuffCalCulateCRC(pCharx2         ;----（，）         1);

Answer 3

我试过用逗号，不好使！
现在就是函数调用时的变量指定的格式不对！
我想在edit里输入表示数组的字符串，然后对输入的数组调用这个校验函数，得怎么写变量呢？

Answer 4

form1.Memo1.Lines.Add(Rt);//---能这样加一个记录类型到一个MEMO里吗? - -!
form1.Memo1.Lines.Add('');

Answer 5

(mc: TMyCRC)
mc = BuffCalCulateCRC(pchar(edit1.text), length(edit1.text));

Answer 6

多谢各位的帮助，现在还有个关键问题，就是我想把结果显示在窗体上，正如上面的兄弟说的，memo显示得是STR型，那Record用什么控件显示？基本的语句是什么那？
问题较多，大家帮帮忙，谢谢了！

Answer 7

(str:string)
setlength(str, 2);
str[1] = chr(mc.Lowbyte);
str[2] = chr(mc.Highbyte);
edit1.text := str;

Answer 8

现在代码变成下面这样

              Lowbyte:byte;                                     //1
              Highbyte:byte;                                 //2
         end;
  TForm1 = class(TForm)
    Edit1: TEdit;
    Memo1: TMemo;
    Button1: TButton;

能够编译过去，但是显示的校验码不对，已经弄了好几天了，就是弄不明白，着急中，大哥们帮帮忙吧，不胜感激！
