Phew! Three more files to go. I just have a few comments:

I saw a LOT of discussion about outputting bytecodes for the JVM. This
may be handy in the early stages, but there are a lot of things about
the JVM that give me a headache. For one, there are NO unsigned integer
types. This may not sound like a big deal, until you try to start
dealing with things like an IPv4 address in an efficient manner. You
either have to use a long (64 bits, and takes up two slots on the JVM
stack) or you have to do some serious shifting and twiddling nonsense.
Plus, most hardware supports far more operations than the JVM does.
I'll have to check what they all are, but I think circular rotate is
one of one. That also may not sound like a big deal either, until you
try to write an MD5 library with it.

I have to go back and reread the IDE stuff, but I think that making
everything GUI is a bad idea. If it is provided it should be an option.
GUI only slows me down.

Until later,

Peter
