Actually, the example wouldn't work for another reason as well.  The
"null flag" is associated with specific fields and is not passed when
passing the field as a parameter.  Coding NULLIND(PARM) within the
procedure will get a compile error since PARM is not defined as null-
capable.  This is a more fundamental restriction.

It's coming.  It's just not in V4R1.
