I totally don't understand: you are saying
1) TeX was developed on TOPS-20 systems
2) tex.web contains code which was appropriate on the system where TeX
was originally developed (§26 is one example).
3) and then you are saying that the code for getting filename was not
implemented the TOPS-20 way in tex.web WHY???
In summary, I don't understand how to get file descriptor when `E' is pressed.
Is it cur_file or what? How was this supposed to work? Is there any
in existence that uses this (simple and straightforward) approach?
(Because on Linux there is a way to get filename from filehandle and I
to use this approach.)
