MPIOK(DGDFN,DGICN,DGLST) ;return non-local LST and ICN
 ;This function retrieves an ICN given a pointer to the PATIENT (#2)
 ;file for a patient.  When the ICN is not local and the local site
 ;is not the Last Site Treated (LST), the LST is retrieved as a
 ;pointer to the INSTITUTION (#4) file.
 ;  Called from SNDQRY^DGROHLR
 ;
 ;  Supported DBIA #2701:  The supported DBIA is used to access MPI
 ;                         APIs to retrieve ICN, determine if ICN
 ;                         is local and if site is LST.
 ;  Supported DBIA #2702:  The supported DBIA is used to retrieve the
 ;                         MPI node from the PATIENT (#2) file.
 ;
 ;  Input:
 ;    DGDFN - IEN of patient in PATIENT (#2) file
 ;    DGICN - passed by reference to contain national ICN
 ;    DGLST - passed by reference to contain LST
 ;
 ;  Output:
 ;   Function Value - 1 on national ICN and non-local LST, 0 on failure
 ;            DGICN - Patient's Integrated Control Number
 ;            DGLST - Pointer to INSTITUTION (#4) file for LST if LST
 ;                    is not local, undefined otherwise.
