Note: The 'XLISP Plus functions' listed on this page are not a regular part of Nyquist. Most of them try to make XLISP more compatible with Common Lisp. I have copied the XLISP code to the related reference pages so you can decide yourself wether you want to use it or not. To use it just simply copy the code from the screen to your 'init.lsp' file.
