Ooooh, good question...

Try the 5.0 Communicator at
http://docs.hp.com/cgi-bin/doc3k/B3021690189.13992/55.  This attempts to show
how ACDs are the underlying security mechanism that bridges the worlds of MPE
and POSIX.

Also try :XEQ POSIXCBT.LSN.SYS.  I *highly* recommend this self-paced training
as a very basic intro into the POSIX HFS.
