Sanitize End Sectors?

     I need to send some files out.  I need to wipe the ends of the 
end-sectors with zeros (or circumflexes, or anything).  This is
in case there is any sensitive info carried over into them from
a previous disk volume that had sensitive info.

     There was a similar flap several months ago over Prodigy.

     Is there a DCL batch file or other utility to do this?

     Is there a FAQ for this newsgroup?

     Is there an Internet FTP site for DEC-VAX stuff?

     Does "High-Water Marking" have anything to do with this?
If a disk volume is set to "Overwrite-on-delete", will this fix
this problem.  Does the VAX environment have these features and are
they commonly used for this?

     Thanks,
     Walt Dence
