I recently was requested to write an app to access data from a mainframe (AS/400). The problem is I have no idea how to perform this process. I will be using selected information (object ID's) from a Keyfile server and accessing the information on the mainframe if it is there. The mainframe has a RUMBA interface. I know that this is a vague description of what I need, but any light that may be shed upon my path will help. I don't want to add any other interface software, I need to be able to add the interface through the VB app I am creating.
