problem with OPENURL [message #26367]

Hi

I'm having a problem with OPENURL.

Using the example code

------------
PRO URL_DEMO, url=url

;
; Make sure the URL does exist.
;
IF N_ELEMENTS(url) EQ 0 THEN url =
' http://debian/datagrabber/servlet/results?query=show+tables& amp;format=openurl'

; The call to OpenURL
;
OpenURL, url, unit=unit

Reading and writing the content of the URL file

str = ''
ON_IOERROR, done
WHILE 1 DO BEGIN
READF, unit, str
PRINT, str
ENDWHILE

done:

END
---------

I get the error message 'Invalid drive specification', though the program
has read the page and printed it to the screen. If I comment out the code
to read the data (ie leave only OpenUrl,url,unit=unit) then it still prints
the contents of the webpage to the screen. Is this something to do with
temporary files.

Help!
