Steve,

Make sure you launch "ntl" first to set up the shared color map for
GEMPAK. This will allocate all the colors for all the GEMPAK programs
and will ensure that you don't run out of colors in the middle of
a session.

When you launch ntl, it will tell you if you have enough colors in
advance. If you don't, it will tell you how many you do have.
You can cut down the number of colors used for satellite images
(from the default of 95) using the -s option, eg "ntl -s 64" to
use 64 colors for satellite images.


Once you launch ntl, you can launch garp either from the button bar, or
from the command line....the shared color map will be used. Once you have
launched ntl, you can go ahead and launch other applications such as
web browsers without having them eat up the colors that GEMPAK will be using.
