I beg your pardon, but I (and my fellow programmers) used it quite a
lot.  I remember a memory test program I wrote that kept relocating itself
around a half megabyte board (a big deal then).  That program made extensive
use of multiple indirections.

Of course the part about the Nova I *really* enjoyed :) were the auto-
increment and auto-decrement locations in memory.  Many a time a programmer
would stop by wondering why their data kept changing value every time they
looked at it.
