connect to mainframe using applications
I would love to hear from you all, is it possible for me to create an application (preferably in Delphi) that can interact with mainframe?
I am planning to implement,
(1) Basic login features
(2) Directory listing
(3) upload and download files etc..
It is highly appreciated if anybody can throw some light into this. Code samples or ideas are most welcome.

Can you use Telnet to communicate with the system today? In that case you might be able to use the Indy Telnet client component (TidTelnet) to connect and perform perform tasks on the mainframe...
the TIdTelnet component has a SendCmd function, with which you can send commands similar to what you are typing when using the Telnet from the command prompt.
That might be one way to get forward anyway...

I feel I must also add that I'm probably way off with my remark... I actually don't know anything about OS 390, but it sounded like an old system, and therefore I just came to think of Telnet... :)

You are right. The OS 390 is almost 30-50 years old and used in mainframes. No one has ever imagined that this mainframe godfather would survive this longer. The truth is mainframes are still alive Today. :) And there are a number of large corporates (I can't name them, since it is a confidential info) who still use this mammoth architectures, because over 60% percent of their data and legacy code still reside in them. Can't even think about replacing or rewriting the code that is 30-40 years old. Cant imagine to migrate the huge historical data that they may have...
Thank you all for your invaluable comments. I can connect to mainframe using FTP ans well as telnet. So i guess this would be the workaround. I will give a try in 2-3 days using these components. Thanks again for your comments.

thank you.
But how to implement connection depends on the special kind of mainframe.
What mainframe do you want to connect to???
