Brian Walker writes that pressing ALT-HELP again after pressing it
once will stop the current screen dump.  However, this appears only
to be the case if the printer is on.  I have to wait 20-30 seconds
if it is not on for control to be passed back to the main program
if the printer is not on. Somehow I find this an unacceptable
amount of time.
   BTW:  There does not appear to be a vector for installing your
own screen dump routine.  I make this assumption after studying the
BIOS listing in Internals.  However, using a VBI routine which checks
_dumpflag will suffice for this purpose.

ATARI: Will the order of executing all routines in the VBI queue
       and then checking _dumpflag be maintained in TOS 1.4?
