I am developing an informational display using hypercard on the
effects of air pollution.  Part of this display involves the
display of the current air quality, using a national instruments
A/D board and the suitable monitoring equipment.  What I would like
to be able to do is to have the stack log data every N minutes or
so, while simulataneously maintaining the informational display.
In other words, I need some kind of system message to put in the
stack script like " on timetick .."so that the users can be doing
something else in the stack.  What I really need is multifinder,
but I can't wait that long.  I don't want to do any busywaiting
(do forever..is it time yet? ..end do). Is there any existing XFCN
or XCMD available that would do this? Could it be done?
I was planning to use on idle to approximate a regular sampling
interval.  Any ideas?
