- What the program does:
-
- When a program such as !Spark takes the
- processor for a long time then it would be
- nice if it would give you some kind of
- indication that it has finished processing,
- apart from the normalizing of the cursor. The
- same goes for ADFS when copying, especially
- to a floppy disc.
-
- What this program does is beep (VDU7) if
- anything causes it to wait for more than a
- certain number of centiseconds between
- WimpPolls. It sleeps for up to 50
- centiseconds and then reads the monotic time.
- If the difference between the current time
- and the time measured at the last measurement
- is greater than a certain velue then it
- beeps.
-
- For example, if you set the system variable
- <AlertAfter> in the !Run file to be 400 then
- if any task steals the machine for more than
- 4 seconds then when it returns the machine
- Alerter will beep, alerting you to the fact
- that you now have control over your beautiful
- Archimedes again. The value of <AlertAfter>
- is read every .5 seconds so you can
- experiment to find the optimal value for
- yourself.
-
- It's a very small utility, yet it takes 16k
- of wimpslot as that seems to be the minimum
- that a basic program can take. Anyone know
- exactly why, and is there a way around this?
- I haven't bothered to find out as it isn't
- really important but I would like to know.
