I updated AppleX with some additional documentation today. But sadly, my 
creative writing project is over for the most part and I am in post-partum 
mode now, so if you want a snapshot, tomorrow would be a good time. Unlikely 
to change much for another 3 years though:)

You probably would have appreciated this about 3 or so years ago. I 
disappeared after I got too busy with my fishing business around the time 
you were trying Orca C. (How did that go by the way?)

The ranks have thinned considerably around here, but I still needed to get 
the Double-Res Graphics stuff done to a reasonable level even if I am the 
last Aztec standing. Somebody needed to write it down in one place for the 
archaelogists. I gues I am the archaelogist too, come to think of it.

There were some loose ends that I needed to tie-up and some of them had to 
do with your old quest about 80 column mode...

1. How does a C programmer work with 80 column text and Hi-Res (HGR) 
graphics in a SYS program?

2. How does a C programmer work with 80 column text and Double Hi-Res (DHGR) 
in a SYS program?

3. How does a C programmer work with Double Lo-Res Graphics (DLGR) and 80 
column text in Mixed Text and Graphics Mode in a SYS program?

And More...

On top of which...

4. How does a programmer read and display a ProDOS directory and indeed use 
ProDOS file services?

The screen capture stuff was also an interesting exercise which led to some 
burning discoveries:

5. The monochrome bitmap displayed in DHGR is exactly the 4-bit color values 
of the pixels since colors in DHGR do not use the high-bits.

6. When in DLGR Auxiliary memory,  the Lo-Res color index requires a 
circular shift.

Ironically as well, it was my omission of monochrome DHGR and the request of 
a Apple II programmer who isn't even a teenager yet that triggered whatever 
point of completion I achieved this go-round.

So thanks for thanking me. You're welcome I think, but I also think you're 
just being polite... and now comes the burning question... should I be 
firing-up my GS and looking at Orca C or should I duplicate what I have done 
with Aztec C65 in cc65, or should I grab a Raspberry Pi or two and muck with 
that, or pursue some 6502 assembly, or all of the above? It's rather like a 
smorg... but I'll be busy with my fishing business soon and I'll be 
disappearing again.... and maybe not soon enough for some folks:)
