.byte: Store an ASCII value as a byte of data

.byte 'A' 

.word: Store a signed integer as a word of data

.word 10

JMP: Jump to a label

JMP label

JMR: Jump to an address stored in a register

JMR reg_1

!0: Jump to a label if the value stored in a register is not 0

!0  reg_1 label

>0: Jump to a label if the value stored in a register is greater than 0

>0  reg_1 label

<0: Jump to a label if the value stored in a register is greater than 0

<0  reg_1 label

=0: Jump to a label if the value stored in a register is equal to 0

=0  reg_1 label

MOV: Copy data from the second register into the first register

MOV reg_1 reg_2

LDA: Load the address of a label into a register

LDA reg_1 label

STW: Store a word of data at a label

STW reg_1 label

LDW: Loads a word of data from a label into a register

LDW reg_1 label

STB: Store a byte of data at a label

STB reg_1 label

LDB: Load a byte of data from a label

LDB reg_1 label
