Faircom C-Tree (Faircom Inc., Columbia, Mo.) will do everything you 
mention.  It comes as C source with porting files for VMS, SysV Unix, 
Xenix, MS-DOS (several compilers) and has been ported to just about
anything that has a reasonable C.  Current version has a queued server
for multi-user systems.  I used it for file management in a system
built on Xenix and ported to Ultrix 2.2, BSD4.3, MS-DOS (Micro C5.1,
Turbo C 2.0), VMS 4.7, Sco UnixV, Interactive Unix.  Distribution is
on MS-DOS format floppies, so you will need to have a floppy reader and
dosread somewhere (Xenix, PC Unixes have this; also Minix).  

Ultrix 2.2 was the "least common denominator" and Faircom does not
specifically claim to support BSD.  My recollection is that it
clean-compiled on all these systems right out of the box and ran all of
the samples, but that the server was flaky on Ultrix.  This was 1988-89;
latest release will probably do even better.  Far superior to C-Isam,
and while it is marketed and distributed with an MS-DOS flavor, it is a
mature product that has a large installed base on non-DOS systems.
Companion product R-Tree is a script-driven report writer language.  

Their D-Tree product is not appropriate here.  I could not get a clean
compile on Ultrix, did not try on VMS.  However, if you are familiar
with ISAM, you will want to program using the C-Tree calls directly.
