Good to know!

This is no longer necessary if you install in Termux
$ apt install termux-exec
With that, hashbangs like #!/usr/bin/pil automagically work! :)
Most scripts now work on Linux and Termux without change.

The windows are maintained by Vip directly and explicitly. Simply positioning
the cursor and writing stuff. Windows are just areas on the screen like
everything else.
As you see in @lib/vip.l, it uses only one single escape sequence for all such
positionings:
(de cup (Y X)
(prin "^[[" Y ";" X "H") )
The other escapes, like character attributes, line clearing, show/hide cursor
and switching between first and second screen are more or less just cosmetics.

It seems to fall back to Java because it finds no existing picolisp.
Not sure what the Java problems actually are, but it is needed anyway only to
build the sr64/*.s files the first time. So I recommend to simply download the
pre-generated "*.s" files e.g. in
https://software-lab.de/x86-64.linux.tgz
