24. INC and DEC Arithmetic Instructions

• Format:

      inc destination
      dec destination
  

• Semantics:

      destination = destination +/- 1
  

• The destination can be 8-bit, 16-bit, or 32-bit operand, in memory or in register.

• No immediate operand is allowed.

• Examples:

      inc    BX       ; BX = BX + 1
      dec    [value]  ; value = value - 1
