Have done some code, but does not work very well

(defun tema-mark ()
  (interactive)
  (save-excursion
    (move-beginning-of-line nil)
    (set-mark-command nil)
    (move-end-of-line nil)))

(defun tema-move ()
  (interactive)
  (set-mark-command 1))

I would like the ability to name a line and then 
move to the named line.  What can I do ?
