Hi Kwan-yin,

>Hello.  I am encountering an error in McIDAS while trying

>DSSERVE ADD SCOTT/IMAGES DIR='goes8*' TYPE=IMAGE

If the image files are in AREA format, the DSSERVE command line
should be:

DSSERVE ADD SCOTT/IMAGES AREA DIR='goes8*' TYPE=IMAGE

I would also recommend adding an informational text message to the
end of the invocation:

DSSERVE ADD SCOTT/IMAGES AREA DIR='goes8*' TYPE=IMAGE "Scotts images

This is caused by ADIRSERV not knowing the type of the image in
the files.  Specification of AREA (if they are, in fact, in AREA format)
as I indicated above is the what ADIRSERV needs to know the type.

Please let me know if the above mod to your DSSERVE command line doesn't
fix your problem.
