C  ****************** FORTRAN77 SUBROUTINE: XXERYD *********************
C
C  PURPOSE: TO CALCULATE THE ENERGY LEVELS IN RYDBERGS ( FROM WAVE NUM-
C           BERS) RELATIVE TO LEVEL 1, AND THE ENERGIES (ALSO IN RYD.)
C           RELATIVE TO THE IONISATION POTENTIAL.
C
C  CALLING PROGRAM:  GENERAL USE
C
C  SUBROUTINE:
C
C  INPUT :    (I*4)  BWNO    = IONISATION POTENTIAL (CM-1)
C  INPUT :    (I*4)  IL      = NUMBER OF ENERGY LEVELS
C  INPUT :    (R*8)  WA()    = ENERGY RELATIVE TO LEVEL 1 (CM-1)
C
C  OUTPUT:    (R*8)  ER()    = ENERGY RELATIVE TO LEVEL 1 (RYDBERGS)
C  OUTPUT:    (R*8)  XIA()   = ENERGY RELATIVE TO ION. POT. (RYDBERGS)
C
C             (R*8)  WN2RYD  = WAVE NUMBER (CM-1) TO RYDBERG CONVERSION
C                              (PARAMETER)
C
C             (I*4)  I       = GENERAL USE
C
C ROUTINES:  NONE
C
C NOTES:     ION. POT. = IONISATION POTENTIAL
