The TM super!--script-- doesn't appear to be an EBCDIC character, but registered trademark, R in a circle, is x'AF' in code page 37. But, as Bob hinted at, this can display differently on different devices; PC5250 vs. other emulator, and IBM vs. other printers.
If the content will ultimately be displayed on a Web Page, you could store the ™ string and it'll convert to the TM symbol which appears as ™ in HTML browsers.
Oh, that just might work for us, Bob. We are trying to convert it for display on a web page. I'll give it a try. Thanks to you too, Dale.
