Roger, Number one:) I plead being distracted by MS-DOS in those years and 
project deadlines but today I did not RTFM so my pleas must surely fall on 
deaf ears...

Billy Potter:) Geez David, I guess I'd better rewrite the FileType Notes 
next and add my own FileTypes:)

A google or two on Payton and cc65 segments also turns-up more good info. 
The segment example he provided compiled and inserted nicely but I am too 
slow at reading and thinking to have this debugged and done today. I am 
certain to be done sometime shortly once I memorize and apply the rest of 
the cc65 documentation on linker configs. It's hard to argue with success.

Of course we all know this in theory. But as always doing something about it 
is both fun and a pain.

I am certain I can't. I am also certain I would bust the cc65 linker if I 
don't work my way through for about a year. Others might do this in a day...

I got that part of it really clearly since that part doesn't change between 
Aztec C65 and cc65. Or on other C compilers.

The obvious affirmation from you, Payton, Mike Mahon, provides some 
authority.

A shift in mindset is the hard part for me, so getting my butt kicked is the 
only way I know to get out of a rut and on the road.

Thanks for taking the time.

Bill
