Re: When is a native OS object not a native OS object?

[CRPence <CRPbottle@xxxxxxxxx>]

  I agree with you that both of those, the *LIB and the database *FILE, 
are native OS/400 object types.  I think what you are missing, is the 
probability that the code was written something like the following [not 
to imply that I know; I do not]:

  dcl is_dir int init 0
  dcl is_lnk int init 0
  dcl is_ntv int init 0
  dcl is_sck int init 0
  ...
  select
   when object_is_container() then is_dir = 1;
   when object_is_socket() then is_sck = 1;
   when object_is_lnk() then is_lnk = 1;
   otherwise do;
     ... if ... is_ntv = 1; ...
   end;
  end select;

  Implication being that probably, once the code determines that the 
object is capable of drill-down, being an effective /directory/, the 
IsNative likely just remains unset, due to how it was coded.  However I 
doubt even if anyone in development agreed, they'd probably just say 
/working as designed/ even though more likely it is /working as coded/; 
or at least state that it is too dangerous to change because someone 
[the OS itself, being most notable] may have coded to that anomalous 
outcome, irrespective of how illogical.  No harm in trying :-)
