I'm working on a school project that includes LISP code examples.  I've 
found many examples in library books, but still need something.

Could someone send me a source code listing of a simple lisp database 
program that I could adapt.  The record structures would be similar to 
an address book.  I must have Name, address, age (integer) and ten 
float numbers (for grades).  I must enable the user to save to file, 
retrieve and update the records.  I must also sort them.  

Any help would be appreciated.

Thank you,

Doug Edwards

I am trying to convert a complex list (list of lists) into a string. The list looks something like this: 
	
		((2 3) (3 4) (4 5)) 

I want it to look like this: 
		
		"((2 3) (3 4) (4 5))" 

Does anyone know how this can be done with relative ease?

Any help would be appreciated.

(format nil "~a" '((2 3) (3 4) (4 5)))
=> 
"((2 3) (3 4) (4 5))"

(stringp (format nil "~a" '((2 3) (3 4) (4 5))))
=>
T

(format nil "~s" '((2 3) (3 4) (4 5)))
=> 
"((2 3) (3 4) (4 5))"

(stringp (format nil "~s" '((2 3) (3 4) (4 5))))
=>
T

see the section of the Lisp printer in your Lisp reference.

Hmmm. How about (format t "~s" (format nil "~s" '((2 3) (4 5))))?

Not sure what happens when you get away from simple atoms like 2 and 3.

Cheers,

(setq my-string (format nil "~A" '((2 3) (3 4) (4 5))))
