Hello again from Gregg C Levine
I've looked at your web pages on the subject of using XXDP to create
that standalone format utility. And it makes sense. All of it.
However, there's a broken link on it, regarding XXDP, and where to
find it. Currently the link which points to the repository at Ibiblio,
is correct. Or even the one you're using as they both work. But the
one that says that the manual, and notes, and the OS, are available
at, is the broken one. It comes up to a file not found error message.
That guy has always had problems with his site, which is unfortunate.
It hasn't returned. 

However, what are you running E-11 under? And which version? The
current one prefers a plain DOS environment, or even a Linux
environment. The older ones, such as the versions stored on the site
here, will work under DOS/Windows, even Windows 98SE, as I've proven.
