[#WLV-393485]: archived datasets

Hi Don,

No worries.

> How is a dataset defined as an "archive" dataset?

This is reall funky...

An archive dataset is characterized by an RT=A setting in a RESOLV.SRV
entry.  The problem is that DSSERVE does _not_ support the specification
of RT=A on the command line.  Here is an illustrative example:

You must specify either YES or NO for REALTIME=
DSSERVE failed, RC=2

So, one must create a RESOLV.SRV entry using RT=[YN] and then edit it to change
the [YN] to an A!

> This will be very useful, so thanks for taking it on.

The work is now in progress.  My intention is to enhance code that Scott L. 
for the archive dataset support.  Interestingly, his work was very restrictive
on when very limited replaceables would be used:

- if RT=A in a RESOLV.SRV definition (and this must be done by hand)
- if DIRFILE= contains (YYYY), (yyyy), (DDD), or (DDD)

The second condition means that the dates used in an archive dataset are limited
to using years and Julian days.  My enhancements will allow use of any date/time
specification supported by the C 'strftime' function.  This is what I used in
the ldm-mcidas package.

Yea, been there done that :-(  Hopefully, I can come up with an elegant
(as opposed to hardwired/kludgy) solution for this problem.
