   You must enable alternate tokens in the project options for this 
syntax to compile.

Or use
	while( ! finished )

I have just written a simple CPP program but it does not compile using
free downloadable borland compiler (borland c++ 5.82 for Win 32).  The program
is here:

//
*****************************************************************************
#include <iostream>

using namespace std;

int main()
{
  bool finished = false;
  int total = 0;
  while (not finished)
  {
    int num;
    cin >> num;
    if (cin.fail())
      finished = true;
    else total = total + num;
  }
  if (cin.eof())
    cout << "Total is " << total << endl;
  else cout << Invalid input" << endl;
}

//
*****************************************************************************

Any ideas what could be the problem?  I have managed to test my
installation by typing a simple hello, world program but this particular
one does not work!!

I corrected one error (else cout << Invalid input" << endl;
changed to
else cout << "Invalid input" << endl;) but there are still
three errors
as follows:

C:\TC\DATA>bcc32 totals.cpp
Borland C++ 5.82 for Win32 Copyright (c) 1993, 2005 Borland
TOTALS.CPP:
Error E2451 TOTALS.CPP 7: Undefined symbol 'not' in function main()
Error E2377 TOTALS.CPP 7: While statement missing ) in function main()
Error E2054 TOTALS.CPP 17: Misplaced else in function main()
Warning W8004 TOTALS.CPP 18: 'total' is assigned a value that is never
used in f
unction main()
*** 3 errors in Compile ***

Thank you

Thank you to both David and Bob.  I used (! finished) and it compiled. 
Also, I found that (using M$ VC++ Express Ediion) one can use an
additional include file like this:

#include <iso646.h>

and to change this:

while (not (finished))

This is because "not" is a function (apparently) in iso/c++ and so
"finished" should be a parameter i.e. its own brackets.

Kind regards,
