C
C  ****************** FORTRAN 77 SUBROUTINE: DXCOMP ******************
C
C  PURPOSE: COMPARES PARENT AND RECOMBINE ION METASTABLE CONFIGURATION
C           EXPANDED ORBITAL VECTORS.  RETURNS .TRUE. IF ONE DIFFERENCE
C           AND GIVES DIFFERING ORBITAL.
C
C  CALLING PROGRAM: D7LINK
C
C  SUBROUTINE:
C
C  INPUT  :  (I*4)   NOCCUM() = OCCUPANCY FOR EACH DECIMAL ORBITAL
C                               INDEX 1-15 OF RECOMBINED ION METASTABLE
C  INPUT  :  (I*4)   NOCCUP() = OCCUPANCY FOR EACH DECIMAL ORBITAL
C                               INDEX 1-15 OF PARENT METASTABLE
C
C  OUTPUT :  (L*4)   LMATCH   = .TRUE.  => ONE ORBITAL DIFFERENCE
C                               .FALSE. => 0 OR >1 MISMATCH
C  OUTPUT :  (L*4)   IORBIT   = DECIMAL ORBITAL INDEX FOR MISMATCH
C
C            (I*4)   I      = GENERAL INDEX
