If you are using the Borland C++ compiler then this is the right group.  If
you are using the Turbo C++ or Turbo C compilers then the proper group is
borland.public.cpp.turbocpp.  For either compiler, a question about the
debugger when debugging from within the IDE but not when using one of the
Turbo Debuggers could also be asked in borland.public.cpp.ide

The most common cause of that is that debug info was not generated.  Enable
debug info in object files and also enable the linker debug option.  Then do
a Project|Build.  If you have used individually set options for source files
in the project, then right click in the project window on each source file
that you've done that to and check that debug info is enabled.

Some lines may not have the little dots or ability to set a valid breakpoint
on them because they do not exist.  For instance:

  if (some_var)
     {
     do this
     do that
     a = 3 * c;
     }
  else
     a = 3 * c;

The compiler would probably not build it as you see it there, but instead
only put in only one line for the a = 3 * c; and the other one would not
accept a breakpoint.

This happens frequently in switch statements where duplicate code,
particularly break or return statements are found in different cases.

Some versions can get a bit confused in switch statements.  The solution for
that is to use curly braces to devine a block for each case like this:

  case someval :
      {
      code is here inside the braces
      break;
      }
