Going back to the way it was (opening text files as text files) works for z/OS. I could propose that but it's not going to solve the problem for the author. If the author can find a more fine grain solution opens text files as text file and works for Windows I can validate the change on z/OS. I'm more than willing to work with the author to fine tune that solution so it works for z/OS too.

Usually working together means doing more than just having the author stab in the dark at a fix for z/OS and having you fix it. Some preliminary investigation on your end on what is actually going wrong would be helpful.
