RE: Frustration!!

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

This is indeed frustrating to learn, Steven, but you'll get there.
You're very close already.

There is a subtle difference between the compiler and the runtime; the
compiler assumes that the class you're trying to compile lives in the
current directory (or one of its subdirectories).

The runtime, though, needs explicit instructions.  The easiest way to
run hello world should be to type "set CLASSPATH=." prior to attempting
to run HelloWorld.
