💩 Oh poop. Screen mode changes done 3 months ago.

About three months ago, I made changes to BASIC Anywhere Machine's screen modes, rolling out the update and completely forgetting to make any kind of heads-up announcement about it.

And I forgot to update a whole bunch of programs to use the new screen modes.

Surprise?

The previous screen modes were the as-is screen modes as implemented in wwwBASIC (as found on Github Dec 27, 2020.  I wanted something more to my liking, so I adjusted them to the ones described in this post.

You can still access the last version of BASIC Anywhere Machine with the old screen modes here (and the documentation for that version here.)

You can compare with the current version of BASIC Anywhere Machine here (and the current version of the documentation here.)  If you had noticed any programs not working: I updated these programs in BASIC Anywhere Machine yesterday to use the new screen modes.  (list of those further down below.)

Also, for your convenience, you can compare the previous screen modes (info below) to the current screen modes in this post.
