I don't know, Paul. You may be right. I've had students in my classes
before who are completely lost even on simple non-language specific
pseudo-code examples. However, others have started out badly, and with
the right tools, have succeeded.

Personally, I don't think w3schools is all that great a learning tool.
It's ok for some stuff, but pretty shallow in their coverage of most
stuff. As for tizag.com - heck, I've never run into that one, either.
I'll have to take a look at it.

But it's obvious Richard is trying, and isn't going to give up. So if I
can point him in a direction which will help him better than newsgroups
do (usenet isn't good for everything!), I will.

And as for his problem - it's a common one I see all the time in my
classes, even from more experienced programmers, and one I make with
embarrassing regularity myself :)
