20030716: Gempak - linux - display drivers

Dusty,

<CR> is an abbreviation for "carriage return". The carrage return
key is also called "Enter" or "Return" on many keyboards.
It is not asking you to type "cr" followed by a return.

The message:
[IP-1] Global file cannot be open for write access
indicates that either: 1) you do not have write permission in the directory
you are working in, or, 2) a file named gemglb.nts already exists and you do not
have write permission for that file.

When using the XW and GF device drivers that use the X server,
if you are loggen in to your console, you should already have write permission
to the X display. You should set the DISPLAY environmental
variable:
setenv DISPLAY :0.0

If you are not logged in to the console, you have to have access to the console,
and the user logged in to the console has to allow you to display there
by typing:
xhost + `hostname`

see the unix man pages on xhost and X, eg "man xhost" and "man X".

If you do not have access to the consoile, you can use the PS or GIF drivers.
See the tutorial page:
http://my.unidata.ucar.edu/content/software/gempak/tutorial/devices.html

Note that when you use a device driver that writes to an output file,
you must use the "gpend" command as decribed at the bottom of the web page
discussed above.
