- This is a rho-version of my 'AntiTask' program...
-
- And this is a rho-!Help text, which means, that it is brief. Very
- brief :-)
-
- AntiTask will allow you to stop multitasking and run a single
- application alone. 'Why on earth would anyone want to do that!?!' you
- may ask.
- This is why: It is very fine, that some programs perform their
- miracles while others continue to run. But for some purposes (eg.
- raytracing, mandelbrots etc.) you are quite aware, that the process
- will take several hours. And you know, that if you move the mouse a
- millimeter, let alone dragging a window or crashing the machine, this
- time will increase. So you don't move the mouse, but go away and do something else.
- Who needs multitasking when you're sleeping? Sysop's, yes, but what about the rest of us..?
- And if you don't need it, there's some speed to gain from disabling
- it. Fortunately, good written programs allow you to click on a 'Single
- task' option, but not all.
-
- Use AntiTask.
-
- When you've started it, you may be able to select the program to
- single-task in the iconmenu. If, it isn't there, you will have to
- start AntiTask *before* the other program.
-
- Once selected, you start the program doing whatever it ought to, and
- click on the AntiTask icon. It should become red, and multitasking is
- now stopped.
- Should you wish to restore the situation, hold down 'Action'. When
- the light becomes green, you are able to proceed.
- Try running one of those 'demo in a window's to see what I mean.
-
- Finally, you should know this:
- This is a definite kludge, and therefore may present problems
- together with certain programs. Until now, I've experienced these:
-
- 1. RiscOs 3 has a new WindowManager, so there's a chance it won't
- work with it. I haven't been able to test this.
- 2. AntiTask grabs the SWI-vector, and certain programs (which does
- the same, but in a dirty way) will not work with it.
- 'TurboFontList' is one.
- 3. The way in which singletasking is done, is by returning from
- a call to Wimp_Poll or Wimp_PollIdle at once. Now, Wimp_PollIdle
- isn't meant to return until after a specified time, so some
- programs get confused when it comes back instantly. This is bound
- to happen, and I don't see a way around it... if you do, say so!
- Anyway, the result is, that when restoring multitasking, these
- programs continue to wait until some time THEY'VE calculated has
- elapsed. So nothing happens for a while after you've pressed
- Action. One can live with it, but it's annoying.
-
- Otherwise, it seems to be ok, so enjoy it while you are away!
