[comp.os.vms] FAL and DAP

david@elroy.Jpl.Nasa.Gov (David Robinson) (02/10/88)

I am looking for more detailed information about FALs and DAP.  I have
found some info in the Micro-fiche about it but my eyes have
grown tired trying to walk though all the code.

Has anyone out there done any work with FALs and DAP?  Specifically
has anyone ever tried to use DAP directly from a user program?
Finally, does anyone know where I can get documrentation on it?

Sure.  You just put nodename:: (or, if proxies aren't enabled or don't
work, nodename"username password"::) in front of the filespec that you
pass to RMS, or to your favorite high-level language's interface to RMS.
You can then do anything to that file that you could do to a local file. 
I'm not sure what would be gained (other than buying yourself a LOT of
work) by having your program send and receive DAP packets itself.

Yes, if you insist.  See my next posting, in response to someone who
wants the order numbers for the DNA Functional Specification documents.
(If you find any capabilities in the DAP protocol that RMS doesn't let
you get to, let the rest of us know, ok?)

Why would you want to?  Anything you could accomplish this way you could
accomplish a lot more easily by using a transparent DECnet link, and letting
RMS worry about DAP.  The only time this would make sense would be if you were
trying to develop your own DAP implementation for a DECnet implementation that
didn't provide one.  I've never heard of one....

DAP and most of the other DECnet protocols are documented, though not in the
standard documentation set - you have to order the manuals.  I don't have my
up-to-date copy of the Documentation Products Directory here, so I can't get
you the order numbers - but the stuff is in there.
