     - [ ] But, it should quickly all the construction of new commands from old ones
     - [ ] Finally, the shell should facilitate saving and loading of disk-images
 - [ ] Write a Bootstrapped Assembler Application in Boo Bytecode Assembly

-# Formal Reqs
-
-
-Run time:
-- Memory needs R/W/E flags - 3 bits
-- Mapping Memory before handing off to lesser privileged processes
-- Needs some understanding off operating mode
-
-
-- Never attempt to pop an empty stack
-
-
-
-Memory
-
-We treat each 64 chunks of memory as a single page:
-
-        0x0000  4800 Pages of Write only Display Memory
-        0x4B000 1 Page of Registers [rip, mode, display, rax, r2, r3, r4, r5, r6, r7, r8]
-        0x4B040 1 Page of Call Stack
-        0x4B080 1 Page of Input Flags (Keys Down etc)
-        0x4B0C0 Dynamic Memory Begins
-
-
-## Instructions
-
-All instructions are fixed length.
-
-
-## Meta Instructions
-
-0x00 - Nop
-0x01 - Update Display
-0x0F - HLT
-
-## Dynamic Instructions
-
-Prefix 0x1#,0x2#,0x3# are given to dynamin register based commands
-
-- 0x1n STORE(n) $Addr (R(n)) -> Addr)
-- 0x2n LOAD(n) $Addr (Addr -> R(n))
-- 0x3n LOADI(n) IMM (Immediate -> R(n))
-- 0x4n INC(n)
-- 0x5n DEC(n)
-- 0x6n ISTORE(n) 
-- 0x7n x LDSTORE Load the Address Stored in n into reg(x)
-- 0x8n x Transfer R(n) to R(x)
-
-## Arithmetic
-
-Prefix 0xa# is given to arithmetic functions
-
-- 0xa1 ADD (R2 + R3 -> RAX)
-- 0xa2 SUB (R2 - R3 -> RAX)
-- 0xa3 MUL (R2 * R3 -> RAX)
-- 0xa4 DIV (R2 / R3 -> RAX)
-- 0xa5 SHIFT (R2 >> R3 -> RAX)
-- 0xa6 AND (R2 & R3 -> RAX)
-
-# Buffers
-
-Buffers are declared in Boo Assembler as `data buffer <label> <length>`
-
-- 0xB0 ADDR (`bclear LABEL`)- Clear the Buffer at Address ADDR.
-- 0xB(N) ADDR (`bappend R(X) LABEL`)- Append the word in R(N) to the Buffer at Address ADDR. Safely handles length.
-Sets `$4` to `0` on success and `1` on failure.
-
-
-# Stack 
-
-Prefix 0xc# allows call stack manipulation. The machine denotes 64 memory addresses at memoo
-
-- 0xc0 RET
-- 0xc1 PUSH Call Stack
-
-
-
-# Jumps and Branches (0x5#)
-
-- 0xE0 JMP $Addr - Unconditional jump to $Addr
-- 0xE1 JMPEQ $Addr (if R1 == R2 jmp $Addr else )
-- 0xE2 JMPNEQ $Addr (if R1 != R2 jmp $Addr else )
-- 0xE3 JMPGT $Addr (if R1 > R2 jmp $Addr else )
-- 0xE4 JMPLT $Addr (if R1 < R2 jmp $Addr else )
-- 0xE5 JMPGEQ $Addr (if R1 >= R2 jmp $Addr else )
-- 0xE6 JMPLEQ $Addr (if R1 <= R2 jmp $Addr else )
-
-## Admin Mode Instructions
-
-Instructions prefixed with 0xF are admin instructions
-
-- 0xF0 UNSET_R $Addr (Sets the 64 addresses after $Addr as Not Readable)
-- 0xF1 SET_R $Addr (Sets the 64 addresses after $Addr as Readable)
-  
-- 0xF2 UNSET_W $Addr (Sets the 64 addresses after $Addr as Not Writable)
-- 0xF3 SET_W $Addr (Sets the 64 addresses after $Addr as Writable)
-  
-- 0xF4 UNSET_X $Addr (Sets the 64 addresses after $Addr as Not Executable)
-- 0xF5 SET_X $Addr (Sets the 64 addresses after $Addr as Executable)
-  
-- 0xFF DROP_MODE $Addr  - Drops from Admin Mode into User Mode (No access to Admin mode instructions)

-0: LOAD_IMM 10
-1: NOP
-2: DEC(1)
-3: JNEQ
