P.S.
Here is the workflow I use to copy data out of debugger: (Replace $F800 with your address.)
1. MD1 F800
2. DATA
3. Ctrl-PrintScreen
4. Alt-TAB to your text editor
5. Ctrl-V
Alternatively, you could just bsave memory and use your favorite hexdump utility:
1. PWD
2. BSAVE "f800.f8ff.bin",f800:f800+FF
3. Alt-TAB to the command line
4. hexdump f800.f8ff.bin
e.g. If you use cygwin64:
\cygwin64\bin\hexdump.exe f800.f8ff.bin
e.g. If you use Python:
pip install hexdump
python -m hexdump f800.f8ff.bin
etc.
