	: Yeah, I think you're right.

This scheme was chosen rather than a full tree to simplify the problem of compatibility with existing DEC PDP-10 software .. We are currently considering the feasibility of implementing a full tree directory structure similar to MULTICS", so it sounds like not.

	: Oh, could be. I assumed there were because of my use of TOPS-20 (on MIT-XX) which had them, and since TOPS-20 was based on TENEX...
