According to the Intel Instruction Set the instruction is:

Code: Select all

CMPS byte ptr ES:[DI], byte ptr DS:[SI] ; or CMPSB
CMPS word ptr ES:[DI], word ptr DS:[SI] ; or CMPSW

No way to use other operands. This is integrated in processor architecture.

You can simply put:

Code: Select all

  REPE    CMPSB

Those operands are optional.

you could

Code: Select all

    PUSH DS
    POP  ES
    REPE CMPSB
