Can you do SFTP from a batch program without invoking the

Scott et al, 
 
Thank you for all your efforts and time spent on helping me.   Scott,
I'm not "in love" with SFTP at all.  In fact, I don't much care what I
use as long as it will not involve storing files or commands or my PUT
statements or anything to speak of in the UNIX/Window-oriented IFS.  I
don't mind putting any sort of "key" there as that won't need
administration very much.  
 
I'd much rather use the regular i5 FTP with some sort of encryption and
get away from the Unix-oriented stuff all together.   Of course,
whatever the i5 sends in the way of an encrypted file has to be readable
by the UNIX side.   If you or anyone has any more ideas and details on
how to do on this, I'd like to know.   I'll call to discuss if you'll
send me your phone number.
 
Thanks in advance,
 
Dave
