It wasn't needed today but maybe needed down the road add a flag to your cpu struct unsigned char FL;

You have a decent base for handling files.

[codejoncode]

int main(int argc, char **argv)
{
  struct cpu cpu;

  if (argc != 2) {
    fprintf(stderr, "usage: ls8 file.ls8\n");
    return 1;
  }

  cpu_init(&cpu);
  cpu_load(argv[1], &cpu);
  cpu_run(&cpu);

  return 0;
}

If you update your main function like this you will need to make an adjustment in your cpu_load but it will be ready for arguments passed on the command line from there the code is a lot like the code provided in this mornings lecture. Major difference is your lines will be added to index's in cpu->ram

Push looks good. This could have been done without using the write function

void cpu_push(struct cpu *cpu, unsigned char val)
{
  cpu->reg[7]--;

  cpu->ram[cpu->reg[7]] = val;
}

[codejoncode]

push(cpu, operandA); in your push should be push(cpu, cpu->reg[operandA]);
