Labels are used to label a memory address. This makes it much easier to refer to memory addresses which hold data or instructions.

Example 1 - using labels with data:

  • data1 DAT
    • Explanation: The memory address where this data is stored would be labelled data1. No data would initially be stored at this location. If this was the 7th line of assembly code to be compiled then the label would refer to memory address 6 (RAM addresses start at 0)
  • data1 DAT 50
