want to eliminate indicators&suppress code further

Hi
I have written  programs CLP&RPGLE to give an option to User to select Yes/No 
options.
Yes option will give him print and No option will send an email to him.
Can some one try to advise me on how can I eliminate indicators and replace 
with builtin functions in my code, is there anyway still i can reduce my 
code...if possible pls answer..this code what I ve written is working for me 
but nt looking beautiful..
