Go back to the IDE, find the source code of the main program, and right
click on it. Select "Main". Change the option from "display" to
"window", then recompile and link. You will have to force a rebuild, as
the change will not trigger it.

It should work the same in both the IDE and the target machine. Note
that once you go to a window rather than a console, you can use accept
and display with line numbers and attributes, or you can use a screen
section.
