My problem is the 
following: ============================
 
In trying to compile the following simple program 
which uses an array of method pointers -
 
********************************************************************* *PROGRAM *********************************************************************
 
#include <iostream>
 
enum BOOL {FALSE, TRUE};
 
class Dog {    
public:       void Speak() const {cout << 
"Woof!\n";}       void Move() const {cout << 
"Walking to heel...\n";}       void Eat() const 
{cout << "Gobbling food...\n";}       void 
Growl() const {cout << "Grrrrrrr\n";}       
void Whimper() const {cout << "Whining 
noises...\n";}       void RollOver() const {cout 
<< "Rolling over...\n";}       void PlayDead() 
const {cout << "Is this the end of Caesar?\n";} };
 
typedef void (Dog::*PDF)() const;
 
int main() {    const int max_funcs 
= 7;
 
   PDF dog_functions[max_funcs] 
=        { 
Dog::Speak,          
Dog::Move,          
Dog::Eat,          
Dog::Growl,          
Dog::Whimper,          
Dog::RollOver,          
Dog::PlayDead        
};                  // 
this is line 33 where 
the                            // 
compiler flags the error.
 
   Dog *pDog;    int 
Method;
 
   while(1)    
{       cout << "Choose - " << 
endl;       cout << "\t(0) Quit;" << 
endl;       cout << "\t(1) Speak;" << 
endl;       cout << "\t(2) Move;" << 
endl;       cout << "\t(3) Eat;" << 
endl;       cout << "\t(4) Growl;" << 
endl;       cout << "\t(5) Whimper;" << 
endl;       cout << "\t(6) Roll Over;" 
<< endl;       cout << "\t(7) Play 
Dead;" << endl;       cout << "\t\t\t: 
";
 
      cin >> 
Method;       if(Method == 0 || Method > 
7)          
break;       else       
{          pDog = new 
Dog;          
(pDog->*dog_functions[Method - 
1])();          delete 
pDog;       }    }
 
   return 0; }

... I recieve the following error messages, 
although it nevertheless compiles fine using Borland C++ Compiler 
5.5.
