Re: No threads in interactive applications?

["Patrick Townsend" <patownsend@xxxxxxxxxxxxxx>]

Simon,

Thanks for your thoughts. The application I want to run on the AS/400 runs
in console mode on *NIX and Windows with the primary thread getting input
from the user. I wanted it to run the same way on the AS/400, but I think
this is not possible. I suppose I'll have to develop some type of
interactive console that communicates with the threaded application running
in batch ala QShell and Java.

Patrick
