- JohnFen 2y agoYes, I've known people who did that as well. Anyone can do it with simple programs and enough experience with the task, but some could do that with complex programs. They could even read hex codes directly and disassemble in their minds. I, like most programmers, never achieved that level of brilliance.
- amichail 2y agoSo did they use padding everywhere to make it possible to edit their code later?
- JohnFen 2y agoNot as a rule. They're entering op codes directly into memory. Occasionally they may pad something with a few NOPs, but that was wasting a constrained resource so it was very rare. What they did was work out the code in their minds before entering anything into the computer.
