RE: Automatic based variables

Until you assign memory to that pointer, your looking at storage that you
don't own. The data structure is just a "template" with no storage
associated with it, initially. Often this I done when you pass a pointer to
a data structure as a parm, then that parm is inserted into the BASED()
keyword.

If I declare a based data structure (EXTNAME and BASED) in a procedure,
what is allocated when I call the procedure?  Common sense tells me it's
just the room for the pointer; that all references to the field are done
via pointer arithmetic.
