How to change the console output from xterm to gnome-shell?

I have Visual COBOL 3.0 personal edition installed on RedHat Enterprise 7.4 to learn COBOL language.

I use COBOLClass_Eclipse to start.

When I run the sample project, it starts xterm windows for result output. but I want to change it to gnome-shell.

I did not find how to switch it in Preference.

I hope someone might encounter the same issue and have a solution.

Really appreciated.
