Howdy again ,
 
with respect to my last query , and the function below, which
I had in my circle.c , ..

--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
bool  test(t, char1)
 TUPLE t;
 char *char1;
{
        extern char * GetAttributeByName();
        CIRCLE * bca;

/*        bca = (CIRCLE *) GetAttributeByName(t, "a");  */

  return strncmp(char1, "1");
}
-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-


                 define function test
  (language = "c", returntype = bool)
  arg is (tutorial, char16)
  as "/usr/local/postgres/circle.o" \g

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

....... Upon running the query           

retrieve (tutorial.all)
               where test(tutorial, "1"::char16) \g

, I get the expected results OK, BUT when I uncomment the above
line in the code i.e " bca = (CIRCLE *) GetAttributeByName(t, "a"); "
and run the same query, the computer hangs ... !

.. has any body else had any good luck with GetAttributeByName(), 
can any body see why the monitor program hangs for me .. ?

All comments appreciated !
Bruce.
