What would be the best laptop to use for XP and LINUX for running VISTA and M programming?
Thanks.
I think a generic description of programming ought to at least adress
object orientation. I know that M doesn't have it yet, but it is a
fundamental concept.

When attempts to write off the right hand side of the Screen are

A polymorphic function is one which changes its behavior depending on
the type and number arguments it receives. It's useful because it is
easier for the stupid humans to remember the Application programming
interface. With polymorphism and operator overloading, you can do some
amazing tricks
OK. So I was quite a bit off on my understanding of the term polymorphism.
I have used this functionality often in c++, but I don't think that
Delphi/Pascal has it.
I guess what I was talking about, then, was simple inheritence. I
don't know if I could implement polymorphism with my scheme.
Polymorphism would be hard in Mumps because it is not strongly typed. The
java implements it is to find out what class is calling it and then
determines the correct function to call inheritance and polymorphism is
close but is determined at different times (one at compile, one at runtime).

You're exactly right. Basically, these two strategies correspond to
flattening a class representation (essentially cloning inherited
behavior) and maintaining a hierarchy that can be searched for an
implementation at dispatch time (not so bad if you cache the
references).

I've heard this described as polymorphism, too. Purists would say it is
not polymorphism because it has nothing to do with runtime type, and
call it overloading instead. Others will say it's simply a different
kind of polymorphism (where behavior depends not upon the object being
operated upon,
Right. We're talking about how to emulate object orientation with a

One of the biggest reasons I don't like this is that programmers always
seem to take shortcuts and bypass the library when it doesn't do quite
what they want. I see this all the time with Fileman. Not infrequently,
