	Many thanks to all those who kindly informed me that system calls
were legal within device drivers.  Now I'll ask the question I meant to
ask:  Are OS9 system calls allowed within the interrupt service routine
of device drivers, ie.  the routine which executes when a device causes
an interrupt.  The reason that I ask this question is because it would
be convenient to debug device drivers by putting output statements in the
interrupt driven routines.  Attempts to do this have not been successful.

	One additional question to all you OS9 system gurus out there.
Are device drivers and there associated interrupt service routines subject
to time slicing, as are normal processes?

				Thanks
