 Re: F83 multi-tasking

But there is also a difference between multi-programmer and multi-user.  For
example, F83 could be used to implement a multi-user system for several data
entry operators inputting data forms.

Multi-programmer is a different story.  I'm always more productive when I am
free to crash the system, execute EMPTY-BUFFERS , run system diagnostics,
change the disk(ette)s, etc.

"Stole"?  Just what do you mean?  Are you saying that round-robin scheduling
is proprietary to Forth, Inc.?  Or that there is copyright violation?  And
that Forth, Inc., was involved in design decisions of F83?  I'm not familiar
with the history of the F83 multi-tasker, but didn't Perry publish it in the
1983 FORML proceedings?
