IBM came out with PC-DOS 7.0 around 2000, it had fixes for the Year 2000 plus REX language. I still a copy of it somewhere.
I also note that.
Probably typo mistake from author?

Again, I was there. No. Microsoft stopped updating MS-DOS 6.0 at 6.2.2.
I never saw DOS 6.3 ( There was a PC-DOS 6.3, which I think was unchanged except for "Disk Compression" . Next thing was the DOS 7.0 used to boot Windows 95 FE.

Yeah 6.3 does not ring a bell here either
PC-DOS had a 6.3, but as far as I know, MS-DOS only went to 6.22 before going to 7 (which was not shipped standalone).
