The MacOS is a "non-preemptive" multitasking OS. This means that a well written, and well behaved, Macintosh program voluntarily gives control back to the system at regular intervals so that it can service other tasks. It was pretty good technology in 1984 for a small, consumer oriented computer, especially considering that the Mac was light years ahead of DOS. MacOS X is based on Unix and will be a true hardware driven multitasking OS. A smiley Mac face on Unix? It's about time! -Allan Tom Ritchford wrote: > email@example.com wrote: > > >No MacOS as of yet does multitasking. > > [blah, blah] > > Gah, enough of this stuff!
