My understanding of "roundtrip conversion" is that every code point in the from CCSID translates to a unique (possibly "meaningless") code point in the to CCSID so that if for example a customer is so foolish as to transmit, for example, an object deck from z/OS to a PC in "text" format, and then transfer it back to z/OS the same way, he will have a good object deck.
I am running Kirk Wolf's excellent showtrtab with the command showtrtab -s 1027 -t 1208 -q R The results I see include the following: 3F: 1A 40: 20 41: 1A Several other EBCDIC code points also translate to ASCII sub, 0x1a. So the question is if multiple EBCDIC code points all translate to 0x1a, how the heck is this a round trip translation? (I'm not alleging a bug in showtrtab. I am getting the same results with my code and ran showtrtab as a reality check and a clearer example.) Where am I going wrong?
