I am trying to set the current line number to a variable in Elisp but keep getting a void-variable error! The code is: (setq x what-line) I'd also like to set the total number of lines in the buffer to a variable as well, but get the same error?!

<pre class="prettyprint"><code>(setq x (line-number-at-pos) y (line-number-at-pos (point-max))) </code></pre> How to find out about this kind of thing? Try <kbd>M-x</kbd> <code>find-function</code> <kbd>RET</kbd> <code>what-line</code> <kbd>RET</kbd> to see the source code of <code>what-line</code>. Reading <code>simple.el</code> (the file in which <code>what-line</code> is defined) is a good way to get familiar with elementary Elisp programming.
