Re: Java Dropdown Window from with RPG program

David,

You hit it on the nose what I am trying to do. I will elaborate a little
more.

Hardware: model 170
OS/400 v5.1 (soon to be going to 5.2)
Display stations: PC's using client access across a TCP/IP network.
Programs: RPG/ILE old style DDS green screens.

When the users are in an RPG program, I would like to give them "pop-up"
windows that display a selection of data to choose from. As an example for a
field asking for state, I would like the user to press a command key to show
a GUI dropdown application written in Java, which would display the states.
The user can then select the state with a nice GUI interface and that state
would be passed back to the RPG program.

You made mention to data-queues. Do you have any source code example you can
refer me to that might be doing this type of work. Eventually I would like
to convert the old "green screen" programs to all GUI when I get a handle on
what I need to do this.

Thanks.

Nick.
