Owen and Tony,

I grabbed all of these files by FTP (how archaic; ADDE could be used
instead :-) and took a look:

DSSERVE ADD TONY/GMS AREA DIRFILE=/home/mcidas/workdata/GMS5* "GMS5 RAW IMAGES

Once I knew the size, I could specify a correct size from an IMGCOPY
using the STYPE=VISR keyword (I had to know the size since the online
help for IMGCOP says that SIZE=ALL can not be used with STYPE=VISR):

IMGCOPY TONY/GMS.3 MYDATA/IMAGES.1250 STYPE=VISR SIZE=1048 2292
Beginning Image Data transfer, bytes= 2404992
Transferring AREA data outbound, bytes= 2405072

You can see that the output image (in the MYDATA/IMAGES.1250 dataset
element) is of the same size, resolution, date, etc. as the original,
and it is now of type VISR with cal type of BRIT.

If I understood Tony's original email, this is what was desired.  If
it is not, please let me know.

Hot dog, that took care of it. Thanks!
