Hello, Here's a basic looping question and what I thought was going to be a trivial problem. I want to find the smallest number in a list. The function min does not take a list, so I tried loop through it: (defun select (a) (let ((x 0)) (loop for i from 1 to (length a) do (if (< i x) (print (setf x ...

After 2 hours of trying I've figured it out, thanks for the help guys: I still have not found out the issue with ACL, but I think it's safe to say for some odd reason ACL does not want you to put files in its home directory. So bottom line, don't save it there. As for the above issue, I guess the st...

[ 2]> *default-pathname-defaults* #P"C:" [3]> (cd) #P"C:\\Program Files\\clisp-2.49\\" And I also can't change the "read-only" attribute of the directory, but I can delete files though. I'm using Clisp. I tried with clisp and I am nearly there! Though now I am getting ...

Okay, well if you're using Clisp and you can delete that makes me think it's something to do with acl's directory. Guess I'll have to just put these files somewhere else or use Clisp.

Thanks!

Well I am running it through Allegro CL, so the default-directory is CG-USER(3): *default-pathname-defaults* #P"C:\\acl82express\\" Yeah I was thinking maybe it is because of ACL. That directory is the one that is not allowing me to modify the contents of it. That seems awfully limited tho...

I also have such permissions, but you do not seem to be bound by any "windows chains" outside the Program Files directory, etc. Sorry, this is the first time I've really tried working with files. Are you saying there is a way to stop this from happening and allow me to look into the conte...

Actually, looking back at it...I have found that the directory is set to read-only. However, any attempt to change this is not working. I uncheck it and when I come back it has been checked again. I did of course hit apply and ok.

Well I have written to it. I just made a simple .txt file, wrote some text to it, and now I am trying to either delete or rename it. The read-only check box has not been checked and has read,write and modify permissions.

Hmm, I guess I blame windows

Gah, I was hoping you weren't going to say that. I've gone into the file and change it's permissions -- allowing everything. Also went to the directory itself and changed it's permissions -- again allowing everything. Yet I am still getting this error. Is there perhaps a better way to delete files/r...

Hello, I am running lisp on Allegro CL Express Edition and am getting this error when I try to delete this file. Note: the file does exist and I am running this on Windows. CG-USER(12): (delete-file "C:/acl82express/output.txt") Error: deleting "C:\\acl82express\\output.txt" resu...
