IMHO, spirit.ocx doesn't provide OO capability - it does serve as an
enabler, though.
What it provides is the ability to write a VB program that writes an RCX
program. This VB program can be as OO as you want it, but the calls to
spirit.ocx are still rather awkward.
Of course, this also opens the way for other to write their own
development systems (OO or otherwise) on top of spirit.ocx. In that
sense, spirit.ocx is an enabler for OO programming of the RCX, however
actual OO capability would come from this other development system
(perhaps a full GUI application, or even just a set of wrapper classes
around spirit.ocx to be used within VB).
Don't get me wrong - I'm not knocking spirit.ocx. It allows a lot of very
useful things to be developed for the RCX. However, many people
mistakenly believe that spirit.ocx allows you to write VB programs for the
RCX. Quite simply, this isn't true. The VB program you write runs on the
PC. Its output, however, may be commands or even a program that is sent
to the RCX.
As for binaries, NQC supports generating/downloading binary forms of
programs, but this isn't used too often. Source versions of the program
are much more useful to other people, and so far most users are perfectly
willing to share their work. However, if you needed to keep the source
private, you could still generate a binary file containing the bytecodes.
