Hi,
But, was DOS a plagiarism from CP/M? Tim Paterson always said it wasn't...
Well, it was original 8088 code, so no. But it did copy the numbers
used to call the functions to ease program porting. So it copied
parts of the calling conventions and functionality of CP/M, but the
actual code implementing that was new and somewhat different.
So CP/M programs could not run unchanged. And the file system
changed as well. And some functionality was added or changed
as well.
Cheers,
Steve N.
