The best suggestion I can make is to try NAME_$DELETE_FILE. Presumably
you've got the pathname around somewhere. I can't guarantee that this
will work if the object's locked, but the NAME error codes don't say
anything about locked objuects. Best of luck.


	While I'm here, here's a question that's been bugging me for
some time. Can someone explain why it is that whenever the Cartridge
tape is active ALL activity on that node ceases? Here's the set-up:
We have a DN3000 with 73M disk and Cart. Partnered to this node is
a DN3000 mono. with no disk. When the Cart is active even PAGING from
the diskless node halts until the Cart stops! Any ideas why this is?

	Thankx,
	Bruce.
