What does "E2" and "E3" stand for in a program listing?

04 E3
31 E2

These are simply two shortcuts for 1 E2 and 1 E3, in other words 100 and 1000. Omitting the leading 1 saves one byte, but you cannot enter these lines directly: they are synthetic instructions. Simply enter 1 E2 or 100, resp. 1 E3 or 1000, and you're done.

I'm afraid you will have to ask the author about this. Or you may analyze the underlying Javascript source. There is a Boolean variable "append" in the function match_alpha that will answer your question (it writes the append-byte 7Fh if text is appended), but I can't tell you exactly how it works.
