标题：关于取汉字首字母
下面的代码（取汉字首字母）是用delphi写的，
用《星》怎么来实现呢？
代码如下：
function TForm1.py(x: string): char;
begin
case word(x[1]) shl 8+word(x[2]) of
$B0A1..$B0C4:result:='A';
$B0C5..$B2C0:result:='B';
$B2C1..$B4ED:result:='C';
$B4EE..$B6E9:result:='D';
$B6EA..$B7A1:result:='E';
$B7A2..$B8C0:result:='F';
$B8C1..$B9FD:result:='G';
$B9FE..$BBF6:result:='H';
$BBF7..$BFA5:result:='J';
$BFA6..$C0AB:result:='K';
$C0AC..$C2E7:result:='L';
$C2E8..$C4C2:result:='M';
$C4C3..$C5B5:result:='N';
$C5B6..$C5BD:result:='O';
$C5BE..$C6D9:result:='P';
$C6DA..$C8BA:result:='Q';
$C8BB..$C8F5:result:='R';
$C8F6..$CBF9:result:='S';
$CBFA..$CDD9:result:='T';
$CDDA..$CEF3:result:='W';
$CEF4..$D188:result:='X';
$D1B9..$D4D0:result:='Y';
$D4D1..$D7F9:result:='Z';
ELSE
result:=char(32); //返加空值
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
i:Integer;
hp:String;
begin
Edit2.Text:='';
for i:=1 to (length(Edit1.Text) div 2) do
begin
hp:=Copy(Edit1.Text,i*2-1,2);
Edit2.Text:=Edit2.Text+py(hp);
end;
end;
