Hi Justin,

re:

Yes.  The scheduler runs commands.  CYCLE= is a keyword that is pertinent
to the IMGDISP command.

First, it appears that elements in the PUB/MTGLOB04I2 dataset update every hour:

IMGLIST: done

Give this, I would set the interval for running IMGDISP at one hour, not
45 minutes.

The next thing you may want to try to ascertain is when the new image
is actually made available in the dataset.  Note that this in not likely
to be the image time; you would have to keep an eye on when a new image
shows up and add a few minutes to the minute and then setup the time
in your SKE command.

Now, how to incorporate CYCLE into IMGDISP command you want to run
from a scheduler entry.  This should work:

SKE 04/04 0 999999 1:00 "IMGDISP PUB/MTGLOB04I2 CYCLE=1 1 10 00:45 LATLON=14 
-128 MAG=2 SF=YES EU=IRLONG REFRESH='EG GRA=(GRA);MAP FILE=OUTVHPOL GRA=(GRA)'

But, it seems more likely that what you want is:

SKE 04/04 0 999999 1:00 "IMGDISP PUB/MTGLOB04I2 SEQ=1 10 LATLON=14 -128 MAG=2 
SF=YES EU=IRLONG REFRESH='EG GRA=(GRA);MAP FILE=OUTVHPOL GRA=(GRA)'

The IMGDISP invocation using SEQ= should update the frame with the oldest image 
with the
new image.  It will not update any frame is the newest image is already 
displayed,
and because of this, you could run the scheduler command more frequently than 
once
per hour if the time that new images are added to the dataset is not consistent.

Cheers,

Tom
