Re: Future of PicoLisp?

As for ubuntu, maybe you could make a Personal Package Archive (PPA). Its lets you make your own packages that can be downloaded by users using apt-get. Its as easy as downloading the normal packages, but the user must manually add the repository. Here's a useful link:

The order of arguments in diff

I was trying out the diff function and I noticed something: : (diff '(1 2 3 4) '(3 4)) -> (1 2) but : (diff '(3 4) '(1 2 3 4)) -> NIL I think this means that there is an order to the arguments of diff, where the second argument must be the shortest. I wanted to ask if this was correct, and

Re: Why print statement should determine whether I get an error or

Hey Dean, I think that, in general, you want to quote a sym argument to a function when you want to change the value of that symbol. For example: : (setq A 1) # Set the value of A to 1 -> 1 : (inc A) # Evaluate A, *then* pass the result to inc -> 2 : A -> 1 : (inc 'A) #

@Alex I'm surprised that (pick '((A B) (and (= A Value) B)) ListA ListB) is faster than (get ListB (index Value ListA)). It's true that get traverses ListB right after a traversal of ListA, but pick seems to do the same traversal of the same number of elements. The only difference is that pick

Loosing elements in a sorted list

Hi list, I have a problem. Whenever I sort a list stored in a symbol, some elements are erased from the original list. Look: : (setq A (3 2 5 4 1 1 1 1 0 1 2 4 5 )) -> (3 2 5 4 1 1 1 1 0 1 2 4 5) : (sort A) -> (0 1 1 1 1 1 2 2 3 4 4 5 5) : A -> (3 4 4 5 5) The pattern that I've noticed is that

ok, so " ' " is a read macro which expands to a list with the symbol quote as car. I still don't understand how it gets translated into a different printed result, but that is probably because, as you said, I just have not drawn enough memory cell diagrams. I'll keep practising until I get it.

Yeah! that is exactly right! All this time I had tried to use the "?" function like this: (? ((loves Mark @X) (woman @X))) But it returned NIL. So, when you search for a variable that can satisfy more than one predicate, you make a list of predicates (call it PList) and pass it as argument to
