(I've never used LejOS but...)
With LegOS (and I would imagine with LejOS), the advantage is over NQC is
that the language you are programming in is a standard implementation. Hence, you
can compile your program with the specialised calls for motors and sensors
replaced with 'printf' and 'getchar' calls and run it on your PC. Then, you
can use any standard C debugger (or Java debugger in the case of LejOS).
If you use Linux (or the CygWin environment under Windoze), you are even
using the same GCC compiler front-end.
You can't really do that with NQC because it is sufficiently different from
standard C to prevent you from compiling all but the most trivial
of programs using a standard C compiler.
Debugging NQC got a lot easier with the 2.0 RCX firmware because you can
now display the contents of a variable on the LCD. Now you can at least
write different numbers into that variable in different places in your
code and see where it is executing.
