[Coco] Looking for source to Multiview Line Drawing Demo

Multivue (gshell) IS in asm on the NitrOS9 repo, though the demo program is not. I would think all the demo program does is to make Os-9 graphics system calls as gshell itself does not actually "draw" anything... it just makes system calls as well.
All real graphics work is done in grfdrv.

Walter,

Based on the Nitros9 project not having real .asm files for Demo and that the Multi-Vue zip file in 
the http://www.colorcomputerarchive.com/coco/Disks/Operating%20Systems/  does not have the source 
code, it looks like you will need to disassemble the program.
Far as I can see after a disassembly, the program is not in C language even though most of the 
references in the MV owner's manual are in a chapter on "C Language Graphics Library Support".

So, "dump" demo to get all the asci comments and then disassemble it. It should not be very hard to 
correct the disassembly with the dump info.
