- Hack is something you do in ten minutes, and I've spent the last two
- years with Executive. Hack is also something that uses illegal things
- to achieve its purpose. Executive is neither. The scheduler in Executive
- only changes task priorities, and there's nothing wrong with that.
- And the scheduler is optional, it can be turned off, you'll then have
- a very comprehensive system control package.
-
- I received a registration from Amiga Technologies GmbH last week. They
- have no plans regarding Executive, but I hope that now, when even
- Windows 95 has got better multitasking than Amiga, a better scheduler,
- like Executive has, would be implemented in AmigaOS.
-
- And Maple, it's not compatible with system legal software. Every user
- has the right to change task priorities. If you would like to run
- Maple at priority lower than -24, you could do that, but then Maple
- wouldn't work. I very much appreciate that Maple has been ported
- to Amiga, but in this case it has a bug, which should be fixed.
- Executive can cope with software like Maple by not scheduling it.

-
- Yes there is, the Maple<-->MaplePlot3D interface should be fixed so that
- it would work regardless of task priorities. I wonder why the MaplePlot3D
- task was given priority -24 in the first place?
