Neil,

See below.

OK. Are the files there?

Front tries to find a frontal analysis as close to the time of the
displayed image/plot.  To do this, it might have to look ahead an hour.
This is the reason for the WARNING about not being able to
open the ASUS1050 file.

OK.

At this point, ASUS1050 exists.  It may be that it does not have any
valid fronts in it.

I recommend that you transition away from the use of FRONT to FRNTDISP
as FRONT is scheduled to be removed from McIDAS with the next release.
FRNTDISP is an ADDE command; it uses the RTWXTEXT dataset to get the
frontal information.  If you have setup XCD decoding of IDD data, then
you should have the textual data that comprises RTWXTEXT available to
you on your own ADDE server.  If you do not, then you can setup a
DATALOC to point at a remote ADDE server.

For, instance:

DATALOC ADD RTWXTEXT papagayo.unl.edu
FRNTDISP NACONF LATEST

DATALOC ADD RTWXTEXT adde.ucar.edu
IMGDISP RTIMAGES/GW-IR LATLON=32 120 MAG=-2 EU=IMAGE REFRESH='EG;MAP H'
FRNTDISP OLAY FRAME

Please let me know if you need help in setting up local access XCD
generated RTWXTEXT data on your system.
