 Well, I still would have liked to see a little explanation as
 to what was going on.   If I see something that doesn't look
 right to me, I just going to blast about it.  It worked great
 this time.  It occurs to me that trying to tell someone they
 are wrong when they are right is great way to get lots of
 information on the subject.
 Here's something I'm not clear about...
#include <fstream.h>
int main( void )
{
    ifstream source ("infile");
    if(!source)
        blablabla...
 When is the file opened in that snip?  Is the reason this works
 the same as why the next line works?
 Because the filename is hard coded?   In other examples I have been
 looking at where the filename must be supplyed by the user at runtime
 the files are opened using this syntax...
  ifstream infile;
  infile.open( argv[1]. ios::in )
 Can you give me a few words about how this works?

 It sounds very good indeed!

 OK.  I trust you.... well, as far as coding is concerned. ;-)
 Actually that makes a lot of sense to me and helps to tie together
 some of the reading I have been doing.
everywhere.
(gcc?).
 Well, I tried it with BC++ 3.1 and it's looking more and more
 like a C compiler all the time.   I'll stick to MSVC 5 from now
 on.  That way if I work in the Visual Studio I'll have all the
 references right there.  In fact I'm going to take some time to
 read through the docs about the string and io classes.
