Answer 1

You need to introduce the CHCCTL keyword, and a variable definition for each choice. See CHCCTL (Choice Control) keyword for display files on the IBM website for details and examples.

You might greatly benefit from finding and working through the Application Display Programming PDF, where such techniques are presented.
