7. Data Allocation Directives

• Five define directives allocate memory space for initialized data:

  • DB Define Byte, allocates 1 byte

  • DW Define Word, allocates 2 bytes

  • DD Define Doubleword, allocates 4 bytes

  • DQ Define Quadword, allocates 8 bytes

  • DT Define Ten bytes, allocates 10 bytes

• Examples:

      value     DW   25159
      Total     DD   542803535
      float1    DD   1.234
