Lisp Tutorials?

I was wondering if there were any good Common Lisp tutorials, that won''t come up as 404 errors...And another thing, Corman Lisp - I tried to execute some of the examples, but a DOS window didn''t pop up, all that happened was an output on the main project file itself, and I know one of them is supposed to plan a .wav file called hellowin with it, because I searched the file itself. When I renamed it as an .EXE, it complained, and .... didn''t work. Any help?

Uhmmm.... It said in the .pdf that came with Corman Lisp, that if you put in (+ 20 30) and press the execute key, you will get the results...

Is this on the worksheet? If so, when I press ENTER nothing happens...

*sigh*

EDIT - but when using the Corman Console..the results DO happen..so ..... ..... what is the worksheet used for? How do I compile files in the IDE? Do I have to compile them in the Console?

Are you using the IDE?

If so, type:
(setq fruits ''(pears apples bananas))

And press the numeric keypad ''ENTER'' key. This executes the statement.

Now, type:
fruits

And press the numeric keypad ''ENTER'' key. fruits will be evaluated, and the list it evaluates to will be printed.

All Lisp statements are compiled on the fly in Corman Lisp. In other Lisp implementations, this isn''t always the case, but the compile function will compile for you. compile is another function, just like + or * is.

Ahhh I see, very interesting! Wow, that's a neat way to associate one word with a list, it's almost artistic!

Oh and, since I have a laptop, I had to press the function key + the enter key, to get the numeric enter key, bit different but meh, who cares!

EDIT - Yes, I was wondering why does it print a line of characters twice (ie - a string) -- for example --

(write-line "Hello, this is your master speaking...")

will print out as -

Hello, this is your master speaking...
"Hello, this is your master speaking..."

Why is that?

The general goal of your initial sessions with Lisp should be with symbols and lists, such as the fruits example, as opposed to typical C or C++ sessions which involve "Hello World" and factorial examples.

You can also select the code you wish to execute and press shift+Enter.

Because you are in the REPL (the interactive environment), it performs the print to standard output (which is the REPL), and it prints the return value to the REPL. So, the first line is the side-effect of write-line, and the second is the return value.

You''re going to pretend you''re programming with a language like C or C++, aren''t you?

Don''t. Start right in with a different mentality.

Why is that?


One is printing out the string, another is the 'value' of the expression.

[EDIT] Ooops, already have answer in previous few post.

I found that this tutorial was good enough to start: Lisp Primer. But some of the more knowledgeable Lispers might find it inadequate, I don''t know.

As a related note, I initially began with Guy Steele''s Common Lisp and regretted it. The book doesn''t know itself if it wants to be a comprehensive tutorial, a reference, or a language specification, so it''s not recommended.

You mean a
(Hello world)
or

(setq greeting '(Hello world))
greeting
?

Yes. I think that using Lisp to work with symbols and lists will get you ahead faster and get you thinking differently as opposed to thinking in terms of strings and printing. This goes a long way towards helping you think in terms of symbolic expressions, parsed data (you''re working with parsed data, instead of strings), code as data, symbols as data, etc.
