Hi Willy,
Nice explanation about naming.
The issue of 8.3 nomenclature falls under the purvue of the
Standards Committee. Before they can remove that constraint,
they will have to work with the community of tool developers
to understand the impact to their code. I'm not on the
Standards Committee, but I'd guess the biggest issue might
be that non-8.3 compliant files will not work with James'
LDraw program, which is still the gold standard for what is
LDraw compatible.

| (...) Hi Kevin, frankly I never understood how and why a program (I've never used BTW) can set a standard! I don't use Office progs from Redmond but I doubt that the file format for Word2007 has to be compatible with Word for DOS 5.5. Hang on! (...) (18 years ago, 28-Mar-07, to lugnet.cad.dat.parts)
