Is there a way to do multiline comments in Common LISP/MCL?
/* For example, these two sentences would be comments if I was programming in Java. However, I am not using Java because I'm trying to learn LISP and since I don't know how to do this in LISP I am stuck using a lot of semicolons for now. :-) */

Hi Mari, Everything placed between a #| and |# is ignored. Two very good introductory texts on Common Lisp that I've used are: 1) "ANSI Common Lisp" by Paul Graham. Prentice-Hall, 1996. ISBN: 0-13-370875-6 and 2) "Programming in Common Lisp" by Rodney A. Brooks. John Wiley & Sons 1985. ISBN: 0-471-81888-7

this is not so, actually. your statement could easily be construed to mean that the a #| is terminated by the first following |#, but #| and |# comments nest. this means that it is quite safe to comment out an arbitrary amount of code with #| ... |#, quite unlike /* and */ in C, which are useless if the region you wish to comment out may contain another comment.

#| Yes, there is. #| And yes, it nests. |# |#

Btw, if you are commenting out code, you are stylistically advised to use #||....||# since some editors think that |...| occurs in balanced pairs (like "...") and that parens don't have to balance between them; using double-||'s won't affect Lisp at all, but will make some text editors do better paren balancing. When in #||...||#, I encourage use of ;'s or #|...|# for text comments since if the #||...||# is removed, you should have parseable-code left.
#|| ;The entire rest of this message is useless ;and has been commented out.
#| 1) This is a comment. 2) It's not a comment containing code. 3) Parens needn't balance. |#
