C  ****************** FORTRAN77 SUBROUTINE: XXGAMA *********************
C
C  PURPOSE: SETUP LOOKUP TABLES FOR ROUTINES I4JGAM AND R8GAM
C
C           TABLES 'JGAM' AND 'GAM' CAN BE REFERENCED WITH FUNCTIONS
C           'I4JGAM' AND 'R8GAM', RESPECTIVELY.
C
C  CALLING PROGRAM: GENERAL USE.
C
C  INPUT : (I*4)  MXINDX  =
C
C  OUTPUT: (I*4)  JGAM()  =
C                           DIMENSION: REFERENCED BY I.
C  OUTPUT: (I*4)  GAM()   =
C                           DIMENSION: REFERENCED BY I.
C
C  PARAM : (R*8)  P1      = 64.0
C
C          (I*4)  I       = LOOP INDEX.
C          (I*4)  I1      = I-1
C          (I*4)  J1      = USED IN COMPUTATION ( = JGAM(N) ).
C
C          (R*8)  X1      = USED IN COMPUTATION ( = GAM(N) ).
