You may be right that Dos 5 did not contain command history. It has assuredly
been a long time since I studied Dos 5. But you are also surely right about
4Dos. For quite some time back then, I was using NDos (same thing under a
different brand name), and it surely had the command history feature. And so did
Midnight Commander. The other package which might have had the command history
feature was dosshell. That was from Microsoft, as I recall, and came as an
enhancement to Dos 5.0, and was installed on the old 386 when I bought it from
the store. But at this point I have no detailed memory at all about the features
of dosshell.
Point is, being able to scroll backwards through the commend history was
definitely available back then and the feature could be found in more than one
product on the open market.
And, of course, the time period is relevant here. I got the 386 in December
1991. I never did put Windows of any version on that computer. I did put
Slackware Linux on it either late in 1995 or very early in 1996. The reason I
made that switch was that I was fleeing in horror from the "necessity"
to install Win 95. The entire design of Win 95 clashed severely and
fundamentally with my own concepts of what a computer was for and why I wanted
to use one, and its installation would have erased years of my own previously
effective efforts to set up my own computer so that it could be used efficiently
for my own work.
As I said above, though, there simply must be more to this than meets the eye.
The patent surely must be for something more than, or a bit different from,
merely having and using a history list. Surely even the USPTO is not so blind
and stupid?[ Reply to This | Parent | # ]

History was definitely present in MS-DOS 6, via the doskey
TSR application.
While this wasn't turned on by default, it
was present and could be added to
your autoexec.bat.
I'm pretty sure that MS-DOS 6 predates the priority
date on
the patent by at least a few years. [ Reply to This | Parent | # ]
