 Q
 ;
 ; FILE is the file NUMBER of the file in which the pointed to fields
 ;        are being merged (e.g., 2 or 200)
 ; FROM is a root under which paired arrays of FROM and TO ien values
 ;        may be found.  If internal entry number 275 were being merged
 ;        merged into ien 75, and the array name to be used was XX,
 ;        the data would be stored as ARRYNAME(FROMIEN,TOIEN) OR
 ;        XX(275,75).  The call would be
 ;
 ;          D ENTRY^XDRMERG(2,"XX")
 ;
 ;    Any number of pairs may be in the From/To array, and the higher
 ;    this number, the more efficient the conversion will be.
 ;
EN(FILE,FROM) ;
 D RESTART(FILE,FROM)
 Q
 ;
 ; The restart entry point permits the user to specify locations for
 ; continuation of a previously interrupted merge process.  The
 ; first two arguments are as indicated above for the EN entry point.
 ; The next three arguments are optional, and should only be set for
 ;    a restart of a merge which was interrupted in progress.  Even
 ;    then these values could be omitted with minimal impact on the
 ;    first two phases of the merge operation.
 ;
 ; XDRTYPE is an indicator of the phase of the merge process
 ;
 ; SFILE indicates the pointer file number from which processing
 ;    should be continued.
 ;
 ; SENTRY indicates the internal entry number within SFILE from which
 ;    processing should be continued
