Running Lifelines

At a command line go to your working directory
(should match that one you set up for LLPROGRAMS) and simply type
llines . 
note the dot (for current directory) and you get
There is no LifeLines database in that directory.                     ?
    Do you want to create a database there?                               ?
    enter y (yes) or n (no):
Enter yes to get started.

(After this first time, things are more direct since you will then have a database started so you will have one to open).
