Common EBCDIC code pages include 1047 and 037 -- but those are not the only choices. You need to do some reading up on code pages (hint: Google is your friend), and you might want to contact your site support group for assistance.
You need to review the documentation for your emulator, or contact the vendor, to find out how to change the code page with it. Different emulators use different techniques and what works for one does not work for another. Your site support group should be able to assist you with the emulator, too.
