{On DELPHI3, we defined LongWord as LongInt}

Usage£º
Add "Uses RyDp32.dcu" to your program

Note:
'fun' can use number or RY_XXXX, else must be variable.
The last parameter 'buf', that you would transfer the parameter as string,
but you should copy the string to a byte array, for example:

 cstr:='H=H^H, A=A*23, F=B*17, A=A+F, A=A+G, A=A<C, A=A^D, B=B^B, C=C^C, D=D^D';
  for i:=0 to strlen(cstr) do
      mBuf[i]:= Byte(cstr[i]);
  mBuf[i]:=0;
  mFun:=RY_WRITE_ARITHMETIC;
  mP1:=0;
   rt:= Rockey(mFun,mHand[num],lP1,lP2,mP1,mP2,mP3,mP4,mBuf[0]);
