Thanks! I am sure it will compile in GNU C for RISC OS? (If that has an RO3
lib rather than an RO3.7 or RO4 lib--- I use RO under Archie an emulator :-) )

Of coure if I was better at RO programming I'd porbably write an Obey file
to do the whole compile and build... :-)

If it uses Mesa and standard C/C++ it should not be too dificult to
compile and run on RO... Problem area is in tweaking the non Mesa UI calls
to be RO relevant ones... Hmmm... Output of course wouldn't be windows
bitmap but RO Sprite or preferably Draw... Again not difficult in C...
(There is then the minor point of after having ported the L-CAD of porting
other favoured tools as well... Such AS MLCAD... and then Mindstorms and NQC!
(The Arc did have a podule slot that allowed a BBC Micro style user port but
I'm not sure about the RIsc PC...)
But i'll try the ldglite apprach you mention... IIRC having just looked at
the instruction file it includes the URL for the sources.. Whether an Arxc
emulator can read .gz is a different matter? (!Sparkplug?)..
Looking into the LDraw on Risc-OS issue now.... Thanks!!
