Searching IDs in same window

[Rami A]

Greetings,
I have the following code in my dotemacs file which searches the IDs and show 
the results in a separate window "when I have two split windows open".
How do I modify it so I could view the results in the "same window"?

; gid.el -- run gid using compilation mode.
;(require 'compile)
;(require 'elisp-utils)
;(provide 'gid)

(defvar gid-command "gid" "The command run by the gid function.")
(defun gid (args)
  "Run gid, with user-specified ARGS, and collect output in a buffer.
While gid runs asynchronously, you can use the \\[next-error] command to
find the text that gid hits refer to. The command actually run is
defined by the gid-command variable."
  (interactive (list
                ;(read-input (concat "Run " gid-command " (with args): ") 
;confirmation
                (word-around-point)))
                ;)
  ;; Preserve the present compile-command
  (let (compile-command
        (gid-buffer  ;; if gid for each symbol use:

         (lambda (mode) (concat "*gid " args "*"))))
    ;; For portability between v18 & v19, use compile rather than 
compile-internal
    (compile (concat gid-command " " args))))

(defun word-around-point ()
  "Return the word around the point as a string."
  (save-excursion
    (if (not (eobp))

    (let ((beg (point)))
      (forward-sexp 1)
      (buffer-substring beg (point)))))

(global-set-key [f4]          'gid)                          ; defined
