[McIDAS #HDN-934891]: ERAU ADDE configuration and Conference call to discuss equipment purchase

Hi Chris,

OK, I'm glad that I wasn't holding things up.

Keep it with the same ticket id (tracking info you are referring to).

I believe that Chiz came up with the naming scheme.

I'll do this is a separate email not in our tracking system.  This will be 
sometime
later today.

What is the name of your machine?

re: example DSSERVE invocation

Excellent.

The HELP for the DSSERVE command (HELP DSSERVE) presents a list, but that
list did not include the '+' sign.

Maybe yes, maybe no.

I wrote a script that implements the 'current' set of files for our GOES-16 
processing.
I based it on the 'ldmfile.sh' script that I include in the Unidata McIDAS 
distribution,
so the basics should already be in your McIDAS installation.  I could tidy the 
latest
script up and send it to you if you are interested.

It is attached to this reply.  I recommend renaming it to use the .BAT suffix
after you extract it from this email.

re:

Excellent.  I modify RESOLV.SRV directly all the time as it is quicker for me.
Please be careful, however, that you include all of the ','s needed as one typo
will make definitions past the mistake unusuable.

re:

I typically keep about 96 of the most recent images in my 'current' sets.  The
actual number that one should keep depends on the frequency that the images
are updated, and how one interprets 'current'.

re:

McIDAS ADDE works with McIDAS formatted files.  If you want to serve GEMPAK
point files, you can not use ADDE, but you could use the TDS.

Ryan has already made a Python script approach available in the Unidata
section of GitHub under the name ldm-alchemy.  I'd check that out before
reinventing the wheel.

re:
> You said that this version of McIDAS can't serve those, correct?

Correct, but the release I am working on right now can.

re:
> Thanks for your help!

No worries.

Cheers,

Tom
