Thanks, very interesting work!

A question about an example: I didn't find out how the examples/midplay.js is supposed to be run. Just trying "dojs -r examples\midplay.js" displays:

Error: cannot open dir 'undefined'. No such file or directory (ENOENT)

The documentation gave no hint either.

tried both in dosbox and pure dos.

MS-DOS forever!

If I remember right the directory for the MIDI-files is hard coded in the script. If that directory does not exist on your machine you might get that error.
Also: there should have been a stacktrace attached to that error hinting on where in the script it was raised...

does that answer help?
