    GETTING STARTED

    - starting Xi up -

    After typing in 'xi' on a shell the following screen will appear:
    
        +---+ -----
       /   / ----
        -   ----  This is Xi Version 0.5.3
     /   / ---
    +---+ ---
    (  1)>
    
    
    What if Xi doesn't fire up? Hmm... maybe your PATH variable is not correctly set. Figure out where Xi is located and add the directory to your PATH variable.
    To test your X-graphic-device please type:
    (  1)>plot(dincarr(100),sin(dincarr(100)),\line);
    
    After a moment a new X-window should pop up. If not you may have problems with the environment variable XIPATH. Xi normaly checks for it's own location and stores this in the variable XIPATH. If this procedure fails Xi won't be able to start it's X-graphic-device (xigraph). Consequently it is important to set XIPATH to the correct value before you start the programm.
    For example if the executable Xi would be located in /usr/local/xi/bin/xi, you would have to set:
    export XIPATH=/usr/local/xi
    
    Online help can be accessed with the command help i.e.
    ( 2)>help print
    ( 3)>help
    usage: help   : Get the help
           help s               : Switch to short-help mode
           help l               : Switch to long-help mode
    
    You can leave Xi by using the command:
    ( 3)>quit
    
    The command exit has the same effect.
