Sample text

In GNU Emacs version 20 and before, your error message will say: Symbol’s value as variable is void: + The meaning is the same as in GNU Emacs 21. 8 Arguments To see how information is passed to functions, let’s look again at our old standby, the addition of two plus two. In Lisp, this is written as follows: (+ 2 2) If you evaluate this expression, the number 4 will appear in your echo area. What the Lisp interpreter does is add the numbers that follow the +. The numbers added by + are called the arguments of the function +.

In almost every case, one of these options will enable you to pass the right information interactively to a function. ) For example, the character ‘r’ causes Emacs to pass the beginning and end of the region (the current values of point and mark) to the function as two separate arguments. It is used as follows: (interactive "r") On the other hand, a ‘B’ tells Emacs to ask for the name of a buffer that will be passed to the function. When it sees a ‘B’, Emacs will ask for the name by prompting the user in the minibuffer, using a string that follows the ‘B’, as in "BAppend to buffer: ".

1 Arguments’ Data Types The type of data that should be passed to a function depends on what kind of information it uses. The arguments to a function such as + must have values that are numbers, since + adds numbers. Other functions use different kinds of data for their arguments. For example, the concat function links together or unites two or more strings of text to produce a string. The arguments are strings. Concatenating the two character strings abc, def produces the single string abcdef.
