I replaced my display ... with display ... at line x column y. It did change the
behavior. It opened a "screen" window, but all else was the same. The window was
not the command prompt window.
This is the scenario that I am trying to prove in. I have a working Cobol
program that requires a modest amount of configuaration information at startup.
I want to be able to invoke the program via a command prompt window or over a
telnet connection, supply the information required via line oriented prompts,
and then let it compute right along. Perhaps I need a totally different approach?
Cheers,
Rich
