I saw that! Interesting to see Microsoft releasing more stuff as open
source, including more of their DOS catalog. I'd really like to see them
release Word for DOS source code too.

As for GW-BASIC, FreeDOS already includes other BASIC interpreters and
compilers with equivalent or better functionality, so I don't know that we
need to add GW-BASIC. I'm not a BASIC programmer, so I'm open to suggestion
on this. There's pros and cons either way (a big pro is compatibility, a
big con is I suspect no one has GW-BASIC files laying around).

But either way, nice to know it's there. And it should be an interesting
experiment for someone to get this to assemble using open tools.

I wonder if they'll release QuickBasic as open source. That would be REALLY

Overall, it's good to see Microsoft doing this. Especially so because of
the company president last week saying that he now recognizes Microsoft was
on the wrong side of history on open source. Seems like they really do
recognize the importance of open source and are taking steps to be more
open (they've released other things as open source via GitHub that hasn't
hit the news)
