RE: Programming alternatives to the AS/400 FTP command.

[keith mcintosh <keith_eh@xxxxxxxx>]

You could write your own ( RPG IV ) FTP client
program.  Look at some socket programming examples.  I
know there are lots of examples of writing FTP 
clients, in Java, on the i-Net.  This way you 
could "talk" to the server and do exactly what you
want to do. Look at the different FTP RFC documents 
for help with the server commands. 

http://www.faqs.org/

Just a thought.
