It seems I'm getting old. What's the trick here? Is this a trick? Yeah, that is who have done things in the past. That's when I learned programming and then "hacked in" the hex codes on a hex keypad on a Z80. That's when I learned programming on my first 8086. You tried to figured out what caused the least overhead. That meant saving space on instructions and in processing power/speed. But then I learned that this is called Spaghetti code.
