How did the LBNL Software Tools for VMS implement pipes? I'm curious
because DEC itself did a product in the mid-1980s called DEC Shell
that was a VMS port of the Bourne shell and associated utilities. I
wrote a VMS device driver that implemented pipes as a true VMS
pseudo-device, similar to VMS mailboxes but with true Unix pipe
semantics.
