Darren,

You always display McIDAS images by individual band.  You can create
products using multiple bands using IMGOPER.  The output of IMGOPER
is an image containing a single "band", so it is displayable by
IMGDISP without having to specify the BAND= keyword.

>I assume the MAG keyword requires integer arguments.

Yes.  The MAG= keyword results in a sampling of the original image if
the MAG= values are <=1.  For blow-ups (MAG= values greater than 1), the
original pixels are replicated.  The integral values of MAG=, therefore,
specify either the sampling interval or replication factor.
