Getting Started in an Individual Session


Before you start CASCADE, you will need to do three things.

  1. You will need to make sure that your system administrator has assigned you to a CASCADE group. You can check to make sure this has happened by typing the unix command:


    which will display the groups that you belong to. One of these should be the group given to you by your system administrator. In an NFS environment, you can use the yellow pages by issuing the command:

    ypmatch gpname group

    where gpname is the name given to you by the system administrator If your login name is not in the list returned, or if the group doesn't exist, contact your system administrator.

  2. You will need to make sure that an environment variable has been set for the CASCADE libraries. This is done different ways on different systems. The most common way to set the variable is as follows. In your .login file, specify the line:

    setenv CASCADE_LIB pathname

    where pathname is a fully qualified unix pathname given you by your system administrator. It will end with the characters ``CASCADE_FILES''.

  3. Due to the potential multiplicity of postscript viewers (e.g., ghostview, gs, showps) and maybe image viewers (e.g., xv), it has become necessary to address this issue. The solution that we have hit on is to the system to look wherever environment variables indicate. Therefore, you should specify these following lines to your .login file:

    setenv CAS_POSTSCRIPT_VIEWER /usr/bin/X11/showps
    setenv CAS_GRAPHIC_VIEWER /usr/local/bin/xv
