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.

This has been discussed before on this list but the simple answer is
"stop doing it - it will make you go blind".
The DS in the subprocedure is in dynamic storage as are all
subprocedure variables not specified as STATIC. The storage is
released when the subprocedure does a Return. So the fact that it
ever "worked" was either good or bad luck depending on your perspective.
A better approach is to have the caller pass the DS that it wants
filled to the subprocedure as a parameter and have the subprocedure
return a found/not found indicator to the caller.
It is always a bad idea to pass to another routine a pointer to data
that you don't "own".
