The original version of open dos (when it was still caldera dos version
7.01), had a multitasking program you could load on top of the base dos
system that allowed multitasking. I don't recall the name of the
program, and I have no idea if it could be made to run on freedos or
not, but my guess is probably not, since it depended on the caldera
version of some utilities to do it's job. On the other hand, It's
possible those utilities were included when opendos was released, so it
might be possible to obtain said programs and give them a try.
I think it was a shell program that loaded when the pc booted that
allowed the multitasking. I never it got working myself, but I also
didn't try very hard, I do know others made it work just fine though.
There's also a program/version called doubledos, which did this as well,
though I don't know the status of that program at all, so some research
is in order if you want to use that.
PTS dos may have a multitasking stack as well, it's been many many years
since I messed with PTS dos, so I could be mistaken on that, and
probably am, but I do seem to recall it did have that capability if it
was configured properly.
There's also a product called concurrent dos, though I never saw that
version myself, so have no idea how well it worked.
Thenk, there's the most popular method of multitasking dos, which was
the program desqview 386 which was used heavily by many bbs operators,
so they could have multi line bbs systems. (I just used multiple
computers, and ran wildcat),
There was also a shareware program called vm386 that handled
multitasking on dos quite well, that one I did use, and in fact, it
worked too well for me, because when I ran multiple programs, I'd get
speech feedback from both programs, which as you can imagine, didn't
work very well for me, so unfortunately, I had to stop using that
program, since a screen reader was necessary for me to use the computer
due to being blind.
I'm sure there are other programs not listed here that did the trick,
but I have no experience with them, so can't point them out, but perhaps
some judicial googling will turn up others, though upon first glance at
search results myself, I'm not really seeing any, just most pages saying
it wasn't possible, which is obviously not true.

First of all, thanks to all the Freedos developers and collaborators.
I want to know if there is any way or utility in Freedos to have two
applications running, for example an outliner and a text editor, and
be able to switch from one to the other without having to exit the
current application. Thanks and regards. Ramon Riera.
