DOS ain't dead

TSR vs DEVICE= (Announce)

> This might be true for some old DOS versions.

My reference source for this is "DOS Programmers Reference", second edition, by Terry Dettmann, published in 1989. It claims to be accurate through MS-DOS 4.0, the latest version of DOS at the time the book was written. Given what I know about Microsoft, that's probably not something they would have changed in later versions of MS-DOS. However, it's also possible they might have added additional support for some INT 21h functions when they added support for dual EXE/Driver files (I think that was MS-DOS 5.0, but am not positive). I've never seen any kind of reference for that, though.

Anyway, it's certainly a possible point of concern if you write device drivers, but is something you don't even need to worry about with TSR's.
