9. Multi-byte Definitions

• Multiple definitions can be cumbersome to initialize data structures such as arrays

• For example, to declare and initialize an integer array of 8 elements

      values  DW   0, 0, 0, 0, 0, 0, 0, 0
  

• What if we want to declare and initialize to zero an array of a lot more elements?

• Assembler provides a better way of doing this by DUP directive:

      values DW 8 DUP (0)
