Lisp Information

Some useful Lisp resources:

• A short reference manual for Lisp
• CMU Common Lisp User's Manual

The Lisp interpreter that we'll be using is called Allegro Common Lisp (or Franz Lisp). It is installed on the GRACE cluster, so just connect as normal to linux.grace.umd.edu. Once connected, run the command tap allegro81 to get access to the Lisp interpreter. To start up the interpreter, run mlisp. You should now have a Lisp prompt, and you can begin entering Lisp commands and seeing the results.

If you have your Lisp program stored in a file called, for example, helloworld.lisp, you can load the program by entering (load "helloworld") at the Lisp prompt. Note that you don't need to include the .lisp extension in the argument to load the program.
