turtles-own [ value ]     ;; This is some phony turtle variable

;; This procedure creates 15 random turtles and opens a file dictated
;; by the user.  It will erase any pre-existing file.

to setup
  clear-all
  crt 15
  [
    setxy random-xcor random-ycor
    set value 5
  ]
  let file user-new-file
  ;; We check to make sure we actually got a string just in case
  ;; the user hits the cancel button.
  if is-string? file
  [
    ;; If the file already exists, we begin by deleting it, otherwise
    ;; new data would be appended to the old contents.
    if file-exists? file
      [ file-delete file ]
    file-open file
    ;; record the initial turtle data
    write-to-file
  ]
end 

;; This procedure makes the turtles move randomly.  It also changes their internal
;; variable by random +/- 1.  We report the patch coordinates and their internal variable
;; to the file.  To view the file, hit the file-close button and open it with a text
;; editor.

to go
  ask turtles
  [
    lt random 360
    fd 1 + random 4
    set value value + random 3
  ]
  tick
  write-to-file
end 

to write-to-file
  file-print (word "---------- Tick Number: " ticks "-----------")
  ;; use SORT so the turtles print their data in order by who number,
  ;; rather than in random order
  foreach sort turtles [
    ask ? [
      file-print (word self ": pxcor: " pxcor " pycor: " pycor " value: " value)
    ]
  ]
  file-print ""  ;; blank line
end
