MAG4 STATUS CALLBACK (1257)    REMOTE PROCEDURE (8994)

This RPC is called from the Imaging Delphi component when
an image/images have been imported via the Imaging Import API
being developed for use by Clinical Procedures.
This call is used in the test version of Import API, it will be 
replaced in the released version.  In the released version the 
Imaging BackGround Processor will be calling the Status Callback
routine of CP.

• STATARR
  PARAMETER TYPE:   LIST
  REQUIRED:   YES
  SEQUENCE NUMBER:   1
  DESCRIPTION:   

  This array has the following structure:
  STATARR(0)="0^Error message"  or "1^Success"
  STATARR(1)=TrackingID 
       TrackingID was sent as a parameter by CP in the IMPORT() call.
  STATARR(2)=Queue Number
       The Queue Number was returned to CP from the IMPORT() call
  STATARR(3..n) If status is '0^ERROR message" these remaining nodes
  will contain further error information.  Intended for User Intervention
  and debugging purposes.
  

Return is a string, it is of no value.  If this call generates an error,
it will be caught in the error trap.  The Queue Number can still be used
to check the status of the IMPORT, and will have the error information 
that was to be passed to the STATUS CALLBACK routine.
