An operand is the data portion of a 6502 assembly instruction. This is to be distinguished from the opcode, which specifies the operation to perform.

In the example below, JMP is the opcode and $1000 is the operand, and the entire line is the instruction.

0001:4C 00 10  JMP $1000      ; Moves the execution pointer to $1000.
