Re:

   var
      altstatus : integer;  (or hpe_status)
      status    : integer;  (or hpe_status)
   ...
   aif.... (status, ...)
   ...
   if status <> 0
      hperrmsg (2, 1, , status, , , altstatus);

hperrmsg has many modes of operation.  The call shown above will display
the error text associated with the status *or* (if not in the system catalog)
will display a message showing the set number and error number (which you
can use to lookup the error in the AIF manual).
