So to David Nugent do I speak these words:

 #define's are fun things...  Good for making your programs virtually

quite as good as TASM macro's...  Or am I just missing something again?

 The "in word" of AUST_C_HERE...  So far, I've yet to see
anywhere, on fidonet or otherwise, in which that word appears more than
once a year!  Yet in here, it's appeared enough for the rest of them...

 Or maybe it's just that C programmers feel the need to make up for the
rather short length of their favorite language's name?

 There must be a reason...  Somewhere...


 Anywayz, onto matters of much more importance...


 Say, anyone good at explaining how to do that inheritence thing?  (I'm
using both Borland C++, and the Unix G++ these days...)  But in trying to
do the inheritance thing, I seem to be missing something...  I create an
object, but I don't know how to create a second object which inherits bits
from the first. (Or rather, I don't know how to USE the first object's bits
via the second object).  Sheesh...  If anyone can actually understand what
I just said, you're a bloody fantastic person...  :-)

 Lets try an example...  (In pascal, I'm afraid!)

type
  SmallOne= object
    { constructor and all that here }
    Function  InheritedThing(MyOne: SmallOne): Integer; virtual;
    Procedure PolymorphicThing(Blooh: Integer); virtual;
  end;
type
  BigOne= object(SmallOne)
    { the usual stuff again... }
    Procedure PolymorphicThing(Blooh: Integer); virtual;
  end;
var
  SmallThing: SmallOne;
  BigThing: BigOne;

 Given those variables (pretend the constructors have been called and all
that), BigThing.PolymorphicThing(BigThing.InheriedThing(BigThing)) would
pass BigThing to SmallOne.InheritedThing(), the result of which would go to
BigOne.PolymorphicThing().

 How do I do that in C?  These darn BC++ books are no help, and we don't do
it in uni till sometime next year...  And even then it'll probably be
mid-semester by the time we get around to anything that complicated...  :-)
