basic instruction--1, 2, or 3 bytes
index byte for operand A, if operand A is indexed--1 byte
index byte for operand B, if operand B is indexed--1 byte
addressing extension for operand A
addressing extension for operand B
implied operands
Operand A is the operand listed first in the following opcode table.
Operand B is the operand listed second in the following opcode table.
All instructions have at most 2 general operands, so this is enough.
The implied operands are associated with operands other than A and B.
Each operand has a digit and a letter.
The digit gives the position in the assembly language. The letter,
one of the following, tells us what kind of operand it is. */
