...like I once worked on, you had a program with over 800,000 lines of source code...

Can you please elaborate on this? I have a hard time picturing someone or even a group of people writing an 800k line piece of code. I'm not doubting you, I'm just curious what this was for.

800K lines is not particularly big in commercial software terms. Of course it's not one file of 800K lines - a project that size will comprise thousands of much smaller files.
