That whole line numbering thing was such a mess. My Apple IIe line
numbering almost always ended up looking something like this:
1 ...
3 ...
7 ...
8 ...
9 ...
10 ...
100 ...
105 ...
110 ...
500 ...
550 ...
1000 ...
Now, what really gets in the way of fun programming today is all that
"protected memory" nonsense.
