To start the Common Lisp interpreter in your glue account just type "tap allegro60"
run "mlisp"
To load a file type (load "filename")
If an error occurs the debugger is automatically invoked. To exit type (quit)
Thanks to Philip for the following post
I think some of the students might be interested in running Allegro CL natively, and Franz gives out Trial versions. You can run trial version as long as you want (but you have to click a "renew" button every month) with only heap space restrictions. There are versions available for Windows, Linux and OS X. http://www.franz.com/downloads/trial.lhtml . Franz states explicitly that trial version can be used for homework :).
Arguable the best (modern) CL programming environment is Emacs with SLIME, and there's a prepackaged version called Lispbox, which runs on above mentioned platforms pretty much out of the box. http://www.gigamonkeys.com/book/lispbox/ .
There's also a page in the book Practical Common Lisp which explains how to use Lispbox setup http://www.gigamonkeys.com/book/lather-rinse-repeat-a-tour-of-the- repl.html The book is available online, and it's an excellent introduction for anyone who actually wants to use Lisp in everyday programming.
You could probably pass this information along, or just post it on the Lisp resources page.
