Emacs Lisp. Emacs Lisp is a dialect of the Lisp programming language used as a scripting language by Emacs (a text editor family most commonly associated with GNU Emacs and XEmacs). It is used for implementing most of the editing functionality built into Emacs, the remainder being written in C (as is the Lisp interpreter itself).
In computer science, a stack or LIFO (last in, first out) is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the last element that was added.n example is top of stack, or  peek , which observes the top-most element without removing it from the stack. Since this can be done with a pop and a push with the same data, it is not essential. An underflow condition can occur in the stack top operation if the stack is empty, the same as pop.
