How to use CPUlator

• Write the code in the editor
  • Edits can be made in the Editor pane
• File > Save will save a copy of the text in your Downloads folder
• Compile and Load will assemble the program and load it into the memory of the simulated computer system
• Disassembly pane lets you see machine code and gives address in memory of each machine-code word
• Step Into command allows you to execute your program one instruction at a time
• Breakpoints can be set at a specific memory address where you want the execution to pause
  • Useful for debugging or examining the state of the program at certain points, such as before or after a loop or a function call
  • Use Continue command to run the program until it reaches the breakpoint
