//
//  Purpose:
//
//    counter() simply reports how many times it has been called.
//
//  Discussion:
//
//    If you can get a function like this to work, you have made a good
//    start at implementing persistent data.

//  Local static:
//
//    int CALLS: the number of calls.
//
{
  static int calls = 0;
//
//  Increment CALLS.
//
  calls = calls + 1;
//
//  Print it.

  cout << "counter() has been called " << calls << " times.\n";
