By including an ampersand (&) at the end of your command line,  you can run programs in the 'background', meaning that your command tool will give you another prompt and will still accept commands.
   Example:

     With an ampersand                                          Without an ampersand

Note: not all commands need to be run in the background this way. The only time it is particularly useful for our purposes is when starting programs that launch a window(s). Netscape, ArcView, and WordPerfect are good examples of programs that should be started with an ampersand. Conversely, Arc, VI, Imagine, and most Unix utilities (ls, cd, rm, etc) do not need ampersands.

ARCVIEW:  Type arcview & at the UNIX prompt.  Exit by clicking on FILE
pull-down menu with the third (right) mouse button and click on exit.   ARCVIEW differs from
command-line programs such as ARC/INFO in that it is driven by a Graphical User Interface
(GUI).

ARC/INFO EXTENSIONS:

ARCEDIT:  Type arc to access ARC/INFO.  At the ARC  prompt, type arcedit (return) and then display 9999 1.This command creates a graphic window for ARCEDIT.  EXIT by typing q,
in the command tool window (not the black graphic window).  Type q at the ARC prompt to
return to UNIX.

ARCPLOT:  Type arc type access ARC/INFO.  At the ARC prompt, type arcedit return)
and then display 9999 1. This command creates a graphic window for ARCPLOT.  EXIT  by
typing q, in the command tool window (not the black graphic window).  Type q at the ARC
prompt to return to UNIX.

HINT:  GIVE THE COMPUTER A FEW SECONDS TO EXECUTE ANY COMMAND.  IT WILL RECORD ALL HITS ON THE KEYBOARD OR MOUSE IN THE ORDER RECEIVED.
COMMANDS WILL EXECUTE IN ORDER AND YOU MAY HAVE MANY MORE
PROCESSES RUNNING THAN YOU WANT.

To quit program windows:  Imagine windows close in various ways;  it is your job to figure out
how to close each window.  Do Not use the third button in the window status bar to quit.  If
there is a FILE pull-down menu, with"quit",  "exit", or "close" try that choice.  If not, look for
quit or close buttons on the window.  Exiting Imagine correctly is important, because the
program will be left running in the background.  This will take up disk space and make that
license (of which we have a limited number) unavailable to anyone.

It is really hard to permanently damage this program or your data without advanced warning.
If you are worried, ask your instructor before starting; but feel free to explore all of Imagine's
many menus and functions.
