Yep, you're absolutely right.  I was misinterpreting the IDL error
message.  The problem I'm having is that I am defining an object with
one of the data elements initialized as an objarr(1).  Then, later on I
am trying to append another object onto that array.  I think what I need
is a pointer to the object array.
