Does anyone have any suggestions as to how to move forward on this ??

I believe the issue lies in the fact that “rt” and “type=record” are mutually exclusive.

The open mode of “rt” refers to open the file for read-only in “text (character stream)” mode, while “type=record” means to access data one record (native to MVS) at a time.

I recommend, either of the following open modes:
“rt” //open in text mode, for reading one (logical) character at a time.
“rb,type=record” //open for binary, fetch record at a time
