Re: [Freedos-user] the msdos 4.0 sources has some multitasking code
Microsoft itself has only released source for dos versions 1.25, 2.0 and 4.0. There are some commercial dos systems that released source for their versions of dos, such as opendos which was caldera dos, they released their version of dos 7.0, which I do have, as well as PTS dos, which released their last version of dos in source form as well, which I have as well. I can't find any license stuff on the PTS dos source, so I have no idea whether their source can be used in anything other than strictly personal environments, but I did have the opendos sources when they were released, and they were under a standard opensource license back when they were released, but then that decision was reversed for some reason, and further releases of that particular dos (of which I think there was only 1) were no longer opensource, but that doesn't really matter, since the opensource version is still available. That means, on a good day, folks can see at least three ways of doing things in dos (legally), though there were versions of MS-DOS version 6.0 that escaped into the wild in source form, which I did have a copy of at one point, though that hd died many many years ago, and I no longer have those sources. I do recall answering a question on a mud one time about the time/date field in dos, since there was some argument about how large the integer was representing the time field. Looking at ms-dos and opendos sources (I didn't have PTS dos sources at the time), there was a difference in the size of the variable used for that field, though I don't remember which dos had the larger variable type, though I did find it interesting that they used different integer types.

Re: [Freedos-user] the msdos 4.0 sources has some multitasking code
I thankfully never had dos 4.00, though I did have pcdos 4.01, which was a big improvement. over the .00 release. Not sure how/why the 4.00 versions were released, but even then, for some reason, the pc versions of dos were considered to be worlds better than the ms versions. Don't know why, because I never used the same versions of dos crossing pc/ms boundaries, I always had one or the other.
