Not true with _all_ versions of Lynx.  The VMS version will simply create a new 
version of the file and delete it, if a previous version exists.  Moreover, 
links to files just don't exist in VMS the same way as in Unix.  The author of 
this "information" should get his facts straight before making blanket 
statements.
