assembler.
Single quote marks works in the assembler just like
they do in C, except that it only supports a handful
of escaped characters, like '\n', and '\r'.

emulator's assembler.
And removed three pointers, and the linewrap table
from zero page, in SuBEditor.
I moved the linewrap table to address $1000.
And because of finally adding include support to the
assembler, I can now start work on SuBAsm!

emulator some more.
I optimized the emulator by replacing the main loop
from a conditional while loop, to an unconditional for
loop.
|
|
emulator smaller, and faster.
I am also starting to make SuBEditor's source code
more readable.
|
|
It now has a lexer/tokenizer, along with a parser.
I have also made the emulator even smaller.

inserting characters without replacing the old ones.

efficient, and ported SuBEditor to C.
I revamped the opcode table to add another prefix bit
for the addressing mode, finally giving access to all
addresses, without wasting any bytes.
I made the stack based operations more efficient, by
sort of applying Duff's device to it.
And I ported SuBEditor to C, to make it easier for me
to figure out how to implement SuBAsm.

Which I am now calling, SuBEditor.
|
|
I also added a new input testing program called
input-3.s, which contains a mostly working editor.

We're now Free Software!!!

for use of the B register as an operand, for ALU based
instructions.
This allows for both low code size, and high
performance.
This means we can save upto 9 bytes, by just using
the B register for ALU operations, rather than using a
memory address.
The indirect addressing modes, give Sux the abillity
to now use pointers.
Hope you guys have a Merry Christmas!

monitor, and the cursor movement routines for SuBAsm.
|
|
Also added support for moving the cursor arround.
