The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Common on now....it wasn't "messing with it", it was a LEARNING experience.
"Thanks" to all who contributed. Aside from taking a wild guess at the use
of "d_namelen", I still haven't come up with any documentation showing the
issue (at least documentation that meant anything to an RPG pgmr).
However, Scott K's website and tutorial did provide a lot of insight into
the pointers and how/why they are being used.
Thanks again, everyone.

Everything works fine. My problem is I don't understand what
%str(%addr(d_name)) is doing and why it is needed.
So probably messing with it wasn't a good idea <grin>
You are dealing with C functions - so the name string is null
terminated (hex 00) - that is what %STR is doing - converting the
pointer that references the null-terminated string to a "normal" RPG
string. They look the same in debug because unless you display in hex
the X'00' won't show on the 5250.
