How to Run Lisp

Follow the liks to the AIMA website and follow instructions
there to download Common Lisp, or...

Browse www.lispworks.com and download your own personal edition
for Windows or Linux (or Mac), or...

Try to run LISP on the CUIT or CS machines. Instructions for this are below.


Steps to run Lisp programs on CUIT or CS machines:
Step 0:
	Login into your account.
Step 1:
	Execute "lisp" on the CUIT machines to enter Allegro Common Lisp 
	environment.
	Alternatively, execute "clisp" on the CS machines to start GNU CLISP.
Step 2:
	Use "load" function to load lisp files into lisp environment.
	Usage:
		(load "fileName")
Step 3:
	Run your programs by executing appropiate functions defined in
	your program.
Step 4:
	You can exit lisp by typing (exit) if you execute command "lisp" on the 
	ACIS machines, or (quit) if you execute "clisp" on the CS machines.



Example:

  Step 1: After logging into a CUIT machine, enter "lisp"
	after the $ shell prompt and then hit <return>.

		$ lisp <CR>

  Step 2: If you already have the lisp program example.lsp in your current 
	directory (the contents of this short program are shown below), you can load this 
      file by typing the following command after the prompt of the lisp environment:

		USER(1): (load "example.lsp") <CR>

  Step 3: Execute the program by entering:

		USER(2): (rpower-of-two 12) <CR>

  Step 4: Exit the lisp environment by entering:

		USER(3): (exit)



*************************************************

example.lsp:

*************************************************

(in-package "USER")

(defun rpower-of-two  (n)
	(cond ((= n 0) 1)
	(t (* 2 (rpower-of-two (- n 1))))))


*************************************************


Another way is to run lisp via emacs:

Meta-x run-lisp  (i.e. hit 'esc' followed by 'x', type "run-lisp" and you'll be 
                  in lisp mode from which you can load files of lisp code...)

This only works on the CUIT machines and will run Allegro CL.
