To run Common Lisp, you must have /opt/franz/bin in your PATH in your .profile
PAIL is physically located at /opt/pail. Since Common Lisp is only running on the SUNS, this means you can only run PAIL from a SUN .
If you are not in the /opt/pail directory, you can always (load "/opt/pail/pail-load.cl")
All source for PAIL is in /opt/pail (different directories for different systems)
You can get out of PAIL by exiting from the GUI, or typing (excl:exit) at the USER prompt
Don't forget to try a number of systems by running the demos.
