Bill
Your reply and another from Gavin Scott indicate that this
goes away in 6.5. I just upgraded to 6.5 and am seeing the commands
to display and change its state. The version of VOLUTIL is A.02.00,
and MPE/iX is 6.5 with PP2.
Thanks
Bob Schlosser

The following URL has a write up on this:
http://docs.hp.com/mpeix/onlinedocs/30216-90269/00/00/74-con.html
(hope that didn't wrap!)
The check point improvement code operates by keeping a bit map of the
portions of a file that changed so only those portions need to be posted
by transaction management. (that's the very simple explanation :)
This option doesn't exist in 6.5. The bit map method does not scale well
with > 4GB files so it was removed.
Hope that helps
