If you must use them (and yes, I used them to implement a hash in fortran), pointers exist in F90, F95 and F2003. -- TimC GREAT MOMENTS IN HISTORY (#7): April 2, 1751 Isaac Newton becomes discouraged when he falls up a flight of stairs. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
