Hi David,
AFAIK, lejos is a linker and needs a .class file.
The MyProg.class file is the output of the compiler operating on
MyProg.java, which must contain the main() method. lejos also needs a path
to all the other .class files referenced in the MyProg.java It
generates a temporary linked binary file and invokes lejosrun to
download it. The temporary file is then deleted. Which explains why lejos
can't deal with a binary file.
Exactly how all this works when several .class files are named, I don't know.
However, lejos Class1,Class2 ...
does actually result in a couple of programs available in the RCX.
If all you have is the several linked binaries, and not the .class files, we
have a problem, since lejosrun takes only a single file name.
Too bad :o(
