In TinyVM Unix/CygWin edition, you might want to
run the examples, and make changes to them. Right
after you unzip the distribution, you can
go to the installation directory and run:
make (Completes installation)
export RCXTTY=/dev/ttyS0 (Or assign the right COM port for you)
export PATH=$PATH:$PWD/bin
tvmfirmdl (Downloads firmware)
cd examples/hello
export CLASSPATH=. (Indicates where class files are)
tvmc HelloRCX.java (Compiles the Java program into HelloRCX.class)
tvmld HelloRCX -d (Links class files and downloads program)
In a normal Java environment you'd do the following (but it
won't work with this particular program, clearly):
export CLASSPATH=.
javac HelloRCX.java
java HelloRCX
I'd suggest picking up a book on Java for beginners.
The Java Tutorial by Sun is usually recommended in
these cases, but to be honest I haven't read it myself.

P.S. Are you the same Ben Erwin with whom I've exchanged
a couple of emails recently?
